Description
PRIOR APPLICATIONS
[0001] This U.S. continuation-in-part application bases priority on
PCT application PCT/IB2007/001187, filed May 8, 2007, which is a
first filed application in the International Bureau, as well as PCT
application PCT/IB2005/003699, filed Oct. 28, 2005, which in turn
bases priority on Costa Rican patent application number 7573, filed
Nov. 11, 2004.
BACKGROUND OF THE INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to an adjustable fuel power
booster component composition. More particularly, it relates to an
adjustable fuel power booster component composition that increases
power and lowers toxic gas emissions when it is mixed with
hydrocarbon fuels and/or low energy content alcohol based
oxygenated fuels.
[0004] 2. Description of the Prior Art
[0005] Hydrocarbon fuels, such as oil, are not renewable. Further,
the volatile nature, including the fluctuation in price, ongoing
social instability and war in the areas where oil is harvested, has
made the look for other power sources a high priority. Still
further, hydrocarbon fuels, such as oil, emit a high level of toxic
byproduct into the atmosphere. In fast developing countries where
regulations are lax at best, people are seeing their once beautiful
cities turned into chocked valleys of toxic fumes from burned
hydrocarbon fuels. This has sparked a worldwide debate and call for
burning cleaner, reusable fuels or additives that reduce dependency
on hydrocarbon fuels.
[0006] Some of these substituted fuels include alcohol based
oxygenated fuels, which can be produced in most countries from
renewable resources such as agricultural crops or organic waste.
Further, alcohol based oxygenated fuels burn significantly less
toxic byproduct, wherein some produce none at all. Due to these
advantages, there is interest to use alcohol based oxygenated fuels
as main fuels in conventional and preferably non-modified internal
combustion engines. However, the search for an alcohol-based
substitute fuel that does not require the modification of the
traditional oil or gas-based combustible engine has encountered
problems and remains unresolved in the prior art.
[0007] The problems that face the prior art include lower energy
content than conventional fuels that require a highly different
air/fuel mixture. To compensate for the lower energy content and to
be competitive on a "liter to liter" basis with conventional fuels,
alcohol-based fuels would require higher combustion efficiency than
that attained with conventional hydrocarbon-type fuels. With such
lower efficiency, said alcohol based oxygenated fuels are forced to
use more liters per horsepower and their costs can therefore not be
compared in a "liter to liter" basis with other fuels.
[0008] Alcohol-based fuels have a very high ignition temperature
and a very low flame speed. Therefore, the engines require
modification to raise the compression ratio. This solution requires
the modification of engine manufacturing plants around the world
and the engines would have a significantly higher manufacturing
cost. Nowhere in the prior art can an existing hydrocarbon-based
fuel (i.e., gasoline) combustible engine be used with an
alcohol-based or other alternate fuel without some level of
modification.
[0009] Further, when alcohol-based fuels are burned in gasoline
engines, the maximum pressure is obtained at a relatively late
moment, and i.e. when the piston is rapidly descending, thus
lowering the combustion efficiency. Some publications describe the
incorporation of low energy content alcohol based oxygenated fuels,
as the main component in gasoline, and adding explosives, such as
nitro-paraffin, in order to attain a maximum pressure near to the
expansion cycle. By doing so, during combustion, said explosives
liberate approximately double the energy that is liberated by
methanol or ethanol. However, at low speeds the engine knocks,
toxic emissions are produced, the octane number is reduced, and the
risk of having phase separation remains. Even with the additives,
the engine components need modification because the required
air/fuel ratio is different. Also, the combustion chamber requires
modifications due to the significantly higher compression
ratio.
[0010] When alcohol-based fuels are burned in diesel engines, the
cetane number decreases and the engine power decreases. Several
attempts have been made to solve these problems in diesel engines,
by adding moderate explosives such as the widely known "cetane
improvers", with the objective to reduce ignition temperature and
to form premature ignition spots to promote flame propagation.
However, higher amounts of toxic emissions are produced, the risk
of having phase separation remains, and the cost increases. In
addition, there is the chance of the engine malfunctioning, unless
engine modifications are made or some engine components are
changed.
[0011] The inventor is aware of the following prior art wherein
attempts to provide alternate fuels have been made. In those

glycol methyl ether or diethylene glycol methyl ether, as suitable

[0032] All of the above listed prior art disclose the use of
additives diluted in methylal and ethers mixed with alcohol, and

[0033] With that being said, none of the above prior art discloses
or can be combined in way that is obvious to one skilled in the art
to make what is clearly needed to improve upon the prior art. That
is, the prior art does not disclose an adjustable fuel power
booster component composition with a synergistic effect produced by
compounds such as propylene glycol monoalkyl ether or butylene
glycol monoalkyl ether that when mixed in a defined proportion with
a product such as normal propyl nitrate and also combined with a
third component such as dimethyl or diethyl carbonate and then
added to hydrocarbon fuels and/or an alcohol based oxygenated
fuels, has the capacity of increasing power, avoiding modifications
on conventional engines once designed for using hydrocarbon fuels
air-fuel and compression ratios, reducing toxic gas emissions, and
improving cetane number in diesel engines and octane number in
gasoline engines.
[0034] It would therefore be advantageous, and a vast improvement
to the prior art, to have such a booster component that when
blended with main fuels like hydrocarbon fuels and/or oxygenated
fuels, allows for adjustments to the ignition temperature, flame
speed, level of explosivity and cetane or octane number; permits
low energy content components to be more competitive on a "liter to
liter" basis with higher energy content fuels; avoids phase
separation when small amounts of water are present in the
hydrocarbon fuel; produces less contaminant gas emissions;
increases the octane number when used as a gasoline substitute and
the cetane number when used as a diesel substitute; and also
reduces opacity when used as diesel substitute.
SUMMARY OF THE INVENTION
[0035] I have invented an adjustable fuel power booster component
composition, which under specified defined proportions of its
components and when mixed with low energy content alcohol based
fuels to be used in its pure form or in mixtures with hydrocarbon
fuels, enables low energy content alcohol based fuels to substitute
conventional fuels, such as gasoline or diesel, in conventional
non-modified internal combustion engines, and thereby generating a
low toxic gas emission.
[0036] My adjustable fuel power booster component composition
includes the following three components: (A) an ignition
accelerator which is normal propyl nitrate and/or diterbutyl
peroxide that can be replaced with one or more ignition
accelerators of the following less preferred compounds: acetone
peroxide, meta-nitrobenzotadecylamide di or triethylene glycol
dinitrate, and alkyl or cycloalkyl nitrates having up to 10 carbon
atoms, such as allyl nitrate, heptyl nitrate, 2-ethylhexyl nitrate,
butyl nitrate, ethyl nitrate, amyl nitrate and isopropyl nitrate;
(B) propylene glycol monoalkyl ether and/or butylene glycol
monoalkyl ether, that can be replaced with one or more of the
following less preferred compounds: propoxyalcohol and/or
butoxyalcohol wherein said alcohol contains from 1 to 4 carbon
atoms, polyoxypropylene glycol monoalkyl ether or polyoxybutylene
glycol monoalkyl ether with a boiling point in the range from 39 to
190 Celsius degrees for the substitution of gasoline, or in the
range from 39 to 350 Celsius degrees for the substitution of diesel
or oils; and (C) methyl carbonate and/or ethyl carbonate and/or
propyl carbonate and/or butyl carbonate, which may be used and
mixed in any proportion with methylal (dimethoxymethane) or ethylal
(diethoxymethane).
[0037] The three components of said adjustable fuel power booster
component composition can be obtained from both petroleum or
vegetal matter/organic waste (biomass) and oxygen from the air, and
then can be mixed with additives for gasoline or diesel with
lubricants, such as palm oil, dimmerized unsaturated fatty acid,
isoamyl ester, and also amines, antioxidants, other cetane
improvers and corrosive inhibitors.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0038] This invention describes a novel technical approach for
solving the aforementioned problems in the prior art and makes
novel and revolutionary improvements to the state of the art. This
is done by providing a product that improves the performance of
hydrocarbon fuels, as well as alcohol based fuels which have poor
energy content compared to conventional fossil fuels.
[0039] The adjustable fuel power booster component composition
includes the following three components: (A) an ignition
accelerator which is normally propyl nitrate and/or diterbutyl
peroxide that can be replaced with one or more ignition
accelerators of the following less preferred compounds: acetone
peroxide, meta-nitrobenzotadecylamide di or triethylene glycol
dinitrate, and alkyl or cycloalkyl nitrates having up to 10 carbon
atoms, such as allyl nitrate, heptyl nitrate, 2-ethylhexyl nitrate,
butyl nitrate, ethyl nitrate, amyl nitrate and isopropyl nitrate;
(B) propylene glycol monoalkyl ether and/or butylene glycol
monoalkyl ether, that can be replaced with one or more of the
following less preferred compounds: propoxyalcohol and/or
butoxyalcohol wherein said alcohol contains from 1 to 4 carbon
atoms, polyoxypropylene glycol monoalkyl ether or polyoxybutylene
glycol monoalkyl ether with a boiling point in the range from 39 to
190 Celsius degrees for the substitution of gasoline, or in the
range from 39 to 350 Celsius degrees for the substitution of diesel
or oils; and (C) methyl carbonate and/or ethyl carbonate and/or
propyl carbonate and/or butyl carbonate, which may be used mixed in
any proportion with methylal (dimethoxymethane) or ethylal
(diethoxymethane).
[0040] When my adjustable fuel power booster component composition
is mixed with a low energy content alcohol based fuel and/or high
energy content hydrocarbon fuel, in defined proportions and
according to the kind of fuel that will be replaced or mixed, the
impact that my adjustable fuel power booster component composition
has on the entire mentioned fuel mixture is characterized by the
following features: [0041] It becomes more competitive on a "liter
to liter" basis with pure conventional fuels, permitting that
present gasoline or diesel engines could be used without requiring
changes in engines components and that the fuel tank could be
filled totally, partially and alternately with any amount of
conventional fuel. [0042] It works competitively, containing low
cost, highly oxygenated fuels made from biomass. [0043] It releases
propylene oxide and/or butylene oxide from component (B) at a
precise moment before the combustion process occurs, thereby
helping to increase maximum pressure near to the expansion cycle
start. Said propylene oxide and/or butylene oxide is produced from
component (B), that by the ignition precursory effect of component
(A), it is compressed at a high temperature at the end of the
compression cycle. It then experiences thermal decomposition and
releases propylene oxide and/or butylene oxide, which, in addition
to being produced, burns and thereby helps to burn the remaining
fuel, and also induces a rapid volumetric expansion of the gas that
reduces the available space for the combustion of the remaining
fuel. Such reduction of the available space for the combustion of
the remaining fuel produces some effects in the engine that are
similar to increasing the compression ratio; the flame propagation
speed is increased, there is no need for lowering the ignition
temperature of the components that have higher ignition
temperature, and to have a distillation curve similar to
commercially available hydrocarbon fuels. Finally, very high
combustion efficiency is obtained. [0044] It behaves as a
co-solvent, remaining in a single phase even when, in the whole
mixture, small amounts of water are present. Such single-phase
stability is maintained in mixtures with hydrocarbon fuels and/or
alcohol based fuels, even when the fuel is exposed to high ambient
moisture, such as cold weather and limited water filtration. [0045]
It produces combustion at lower temperatures compared to
conventional fuels allowing the manufacturers to use more economic
and lighter cooling system. [0046] It produces a colder flame when
compared to conventional fuels, and depending on the proportions,
it can become water-extinguishable, thereby reducing accident risks
in vehicles catching fire, which in turn allows the manufacturers
to build safer engines. [0047] It can be adjusted to have a larger
octane number than pure gasoline, even when used in a mixture with
gasoline and said gasoline is the main component of the mixture.
[0048] It can be adjusted to have a lower opacity than pure diesel,
even when used in a mixture with diesel and said diesel is the main
component of the mixture. [0049] It can be adjusted to a larger
cetane number than pure diesel, even when used in a mixture with
diesel and said diesel is the main component.
[0050] The preferred component (A) of said adjustable fuel power
booster component composition used in the present invention is
normal propyl nitrate (NPN). NPN can be prepared by reacting
n-propyl alcohol with 70% nitric acid dissolved in ethyl acetate.
During the reaction, the temperature must be kept at 20.degree. C.
and the product can then be extracted by distillation. NPN can also
be prepared by re-acting a continuous stream of propyl alcohol
below the surface of a stirred mixed acid composed of 20% nitric
acid, 68% sulfuric acid, and 12% by weight of water in an open
stainless steel vessel cooled to 0-5.degree. C. Additional mixed
acid is also simultaneously introduced at about a third of the
depth of the liquid. An overflow pipe maintains a constant reactant
level and the effluent product is separated, washed with aqueous
10% sodium carbonate solution, and dried by passage through a
Filtrol packed tower with 50% isopropyl alcohol as the solvent at
0.degree. C. Yield is about 66.5%.
[0051] Component (B) of the adjustable fuel power booster component
composition of the present invention is propylene glycol mono-alkyl
ether and/or butylene glycol monoalkyl ether. Some examples of such
compounds are: propylene glycol monomethyl ether, propylene glycol
monoethyl ether, propylene glycol monopropyl ether, propylene
glycol mono-n-butyl ether, propylene glycol mono-t-butyl ether,
propylene glycol mono-n-amyl ether, propylene glycol mono-t-amyl
ether, dipropylene glycol monomethyl ether, dipropylene glycol
monoethyl ether, dipropylene glycol monopropyl ether, dipropylene
glycol mono-n-butyl ether, dipropylene glycol mono-t-butyl ether,
dipropylene glycol mono-n-amyl ether, dipropylene glycol
mono-t-amyl ether, tripropylene glycol monomethyl ether,
tripropylene glycol monoethyl ether, tripropylene glycol monopropyl
ether, tripropylene glycol mono-n-butyl ether, tripropylene glycol
mono-t-butyl ether, tripropylene glycol mono-n-amyl ether,
tripropylene glycol mono-t-amyl ether, and other compounds of the
same class. Additional examples are propylene glycol monophenyl
ether, and other compounds of the same class. Derivatives
corresponding to 1,2-butylene oxides can be used, including
dibutylene glycol mono methyl ether, dibutylene glycol monoethyl
ether, dibutylene glycol mono-n-propil ether, dibutylene glycol
mono-isopropyl ether, dibutylene glycol mono-n-butyl ether,
dibutylene glycol mono-t-butyl ether, tributylene glycol mono
methyl ether, tributylene glycol monoethyl ether, tributylene
glycol mono-n-propil ether, tributylene glycol mono-isopropyl
ether, tributylene glycol mono-n-butyl ether, tributylene glycol
mono-t-butyl ether, and other compounds of the same class. In
addition, derivatives corresponding to 2,3-butylene and propylene
oxides can be used in alternate embodiments.
[0052] The most preferred compounds are those with boiling points
in a range from 41 to 188 Celsius degrees when they are used for
gasoline and from 39 to 350 Celsius degrees when used for diesel or
burning oil. Propylene glycol monoalkyl ether or butylene glycol
monoalkyl ether can be replaced with the following less preferred
compounds: i) propoxyalcohols and/or butoxyalcohols, wherein said
alcohols have from 1 to 4 carbon atoms; examples include
propoxymethanol, butoxymethanol, propoxyethanol, butoxyethanol,
propoxy-n-propanol, propoxy-iso-propanol, butoxy-n-propanol,
butoxy-iso-propanol, propoxy-n-butanol, propoxy-sec-butanol,
propoxy-iso-butanol, propoxy-tert-butanol, butoxy-n-butanol,
butoxy-sec-butanol, butoxy-iso-butanol, butoxy-tert-butanol; and
ii) polyoxypropylene glycol monoalkyl ether and/or polyoxybutylene
glycol monoalkyl ether with boiling points in the range from 39 to
190 Celsius degrees when used in gasoline, or in the range from 39
to 350 Celsius degrees when used in diesel or oils.
[0053] All of the above-mentioned compounds that correspond to
component (B), when combined in the defined proportion with a
product such as normal propyl nitrate from component (A) and
dimethyl or diethyl carbonate from component (C), under defined
pressure and temperature and prior to the combustion process,
releases propylene oxide or butylene oxide. These compounds are
responsible for the very high combustion efficiency of the
adjustable fuel power booster component composition.
[0054] The propylene glycol monomethyl ether or butylene glycol
mono methyl ether can be produced from biomethanol and glycols
obtained from agricultural crops such as sugar cane, tapioca, corn,
sorghum, etc. The chemical process for the production of said
glycols involves two basic steps. In the first step, there is a
catalytic hydrogenation to convert glucose or a monosaccharide into
sorbitol. The second step is a continuous catalytic process known
as hydrocracking, which uses steam to convert sorbitol molecules
into glycols which are purified by distillation.
[0055] Component (C) of the adjustable fuel power booster component
composition of the present invention consists of dimethyl and
diethyl carbonate which are commercially made from methanol, carbon
monoxide and oxygen in a reactor at moderate pressure and
temperature. This component may be used by mixing it in any
proportion with methylal (dimethoxymethane) or ethylal
(diethoxymethane).
[0056] The adjustable fuel power booster component composition of
the present invention may be used in a mixture with fuels such as
diesel or bio-diesel or with a fuel comprising one or more of the
hydrocarbon components of gasoline from petroleum, synthetic or bio
gasoline, burning oil, mineral oil, vegetal oil and alkoxy-terminal
polyoxymethylenes mixtures, to name just a few.
[0057] The adjustable fuel power booster component composition of
the present invention increases the octane number of the main fuel
by increasing the proportion of dimethyl or diethyl carbonate from
component (C). This component (C) has an octane number that exceeds
120. The adjustable fuel power booster component composition of the
present invention can increase the cetane number of the main fuel
by increasing the proportions of normal propyl nitrate coming from
component (A), which helps to increase the level of explosivity and
flame speed. Said adjustable fuel power booster component
composition also decreases the ignition temperature and toxic gas
emissions by increasing the proportion of propylene glycol
monoalkyl ether and/or butylene glycol monoalkyl ether.
[0058] Therefore, the ignition temperature, and the cetane or
octane number, may be changed by varying the proportion of the
components of said adjustable fuel power booster component
composition to obtain the defined proportion required to trigger
the releasing of propylene oxide and/or butylene oxide in a precise
moment, near to the expansion cycle start, at the moment of maximum
pressure, and prior to the combustion process so as to obtain a
very high combustion efficiency. Propylene oxide and/or butylene
oxide produced by the thermal decomposition of propylene glycol
monoalkyl ether or butylene glycol monoalkyl ether, come as a
result of the confinement inside the combustion chamber and high
pressure and temperature, which is what generates an efficient
combustion. Some racing cars have used propylene oxide, feeding the
engine from a separate tank, for increasing the engine's power
yield. However, this was prohibited due to the high toxicity for
humans and the extreme care required for handling this compound.
Propylene glycol monolakyl ether or butylene glycol monoalkyl
ether, when used as described herein, works as a carrier to
"transport and release" said oxides without the associated toxic
effects during or after the combustion process.
[0059] The defined proportion for each one of the three components
in the adjustable fuel power booster component composition of the
present invention is set according to the operational conditions of
the combustion chamber. The operational conditions of the
combustion chamber in a diesel engine are different that that of
the operational conditions of the combustion chamber in a gasoline
engine. Therefore, when said adjustable fuel power booster
component composition is mixed with another fuel, the defined
proportion for each one of the three components is selected
according to the particular kind of fuel to be used in the mixture.
Thus, the defined proportion of each one of the three components of
said adjustable fuel power booster component composition is
different for a mixture containing diesel and for a diesel engine,
than for a mixture containing gasoline and for a gasoline
engine.
[0060] The process of obtaining the three components mixtures of
said adjustable fuel power booster component composition involves
the mixing of the three components simultaneously or sequentially
without any particular order. Additives can be added before, at the
same time or after the preparation of said mixtures.
[0061] In summary, the compositions of the present invention and
the method for their use, opens avenues for larger use of low
energy content alternative fuels in conventional internal
combustion engines, without the need for modification.
[0062] Specifically, the present invention provides for an
adjustable fuel power booster component composition that enables
high oxygen content fuel components to be used in larger portions
when operating in conventional, non-modified engines, thereby
helping to lower overall fuel cost. Usually the more oxygen content
the fuel has, the less expensive it is. For same air/fuel ratio and
similar density of fuel, increasing the weight of the fuel by
incorporating oxygen costs much less than by incorporating
hydrocarbon compositions. Further, the adjustable fuel power
booster component composition of the present invention, when under
specified defined proportions for its components and when mixed
with hydrocarbon fuels and/or low energy content alcohol based
fuels, increases the fuel's power to the mixture of all of it's
components, has the property of being miscible with oxygenated
fuels, as well as for allowing the vehicle's tanks to be filled
totally, partially, or alternately with conventional fuel.
[0063] Still further, the adjustable fuel power booster component
composition, when under specified defined proportions for its
components and when mixed with hydrocarbon fuels and/or low energy
content alcohol based fuels, for the substitution of gasoline it
increases the octane number, and for the substitution of diesel it
reduces the opacity and increases the cetane number thereof. Still,
even further, the adjustable fuel power booster component
composition of this invention, when under specified defined
proportions of its components and when mixed with low energy
content alcohol based fuels or with low energy content alcohol
based fuels mixed with hydrocarbon fuels, reduces contaminant
production, generates new opportunities for biomass alternative
fuels and creates ways to increase energetic independence from oil
producers, thereby reducing unemployment, increasing
agro-industrial activities, reducing imports in many undeveloped
countries, lowering poverty without increasing atmospheric carbon
dioxide levels, and contributing to avoidance of the effect known
as "Global Warming."
[0064] Another advantage of this inventive adjustable fuel power
booster component composition, which under specified defined
proportions of its components and when mixed with low energy
content alcohol based fuels or with low energy content alcohol
based fuels mixed with hydrocarbon fuels, makes the main fuel burn
at lower temperatures than conventional fuels, allowing the
possibility of building engines with lower quality requirements,
giving manufacturers the opportunity to build engines with a lower
cost, lighter and with a better weight-to-power ratio, and with a
lower cost cooling system.
[0065] More advantages include an adjustable fuel power booster
component composition that, under specified defined proportions of
its components and when mixed with low energy content alcohol based
fuels or with low energy content alcohol based fuels mixed with
hydrocarbon fuels, produces a flame that is colder and can be
easily extinguished with water, reducing accident risks in vehicles
catching fire and giving the opportunity to the manufacturers to
build safer engines. Further, this adjustable fuel power booster
component composition, when under specified defined proportions of
its components can be blended with fuels containing low energy
content alcohol based fuel components, which can be made from
biomass and oxygen from the air, without sacrificing competitive
performance. Even more, this adjustable fuel power booster
component composition, which under specified defined proportions of
its components and when mixed with hydrocarbon fuels and/or low
energy content alcohol based fuels or hydrocarbon fuels, maintains
a single phase even if there is a small amount of water.
[0066] The defined proportions mentioned above for the three
components for the adjustable fuel power component composition of
the present invention in the preferred embodiment range from 0.001
to 99.998% v/v for component (A); 0.001 to 99.98% for component
(B); and 0.001 to 99.998% v/v for component (C) However, in an
alternate embodiment, the ranges are 2 to 16% v/v for component (A)
2 to 16% v/v for component (C) and 68 to 96% v/v for component (C).
Yet in another alternate embodiment, the ranges are 2 to 14% v/v
for component (A); 2 to 36% v/v for component (B) and 50 to 96% v/v
for component (C). Of course, other ranges can be employed to
achieve the same results in the same way and in the same manner.
Therefore, it is understood that the ranges set forth directly
above are not meant to be limiting in the percentage mixtures that
can be employed with the novel adjustable fuel power booster
component composition of the present invention.
[0067] The adjustable fuel power booster component composition of
the present invention can also include meta-nitrobenzoctadecylamide
and/or nitrobenzoctadecylamide. In a preferred embodiment, about
0.3% to about 11% by weight is utilized. These compounds assist in
decreasing corrosion levels and improving lubrication properties to
a level where accelerated deterioration is avoided in the long
range.
