METAL-BASED HYDROGEN SULFIDE SCAVENGER AND METHOD OF PREPARING SAME
Abstract
The present disclosure is related to a family of oil-based dispersions of organic and inorganic metal compounds for use as a hydrogen sulfide scavenger in asphalt, and the preparation thereof. These dispersions comprise organic and inorganic metal compounds, organic solvents, an organoclay suspension agent, an emulsifier and optionally a polymeric stabilizer. The organic and inorganic metal compounds are in the form of micron-sized particles. Copper-based dispersions are particularly effective at reducing the hydrogen sulfide emission of asphalt in the presence of polyphosphoric acid.
