Abstract
This invention relates to the reduction of oxidized sulfur compound (SOX) emissions produced during combustion of sulfur (S)-containing combustible compounds. More particularly, this invention provides a method for reducing such emissions wherein the combustible compound is mixed with an admixture of a water soluble and a water insoluble sulfur sorbent. Use of such admixtures, remarkably, produces a reduction in the SOX level far greater than would be expected based on the activity of each sorbent alone. Extremely viscous hydrocarbons can be burned as preatomized fuels, which can also be mixed with sorbent admixtures. Clean burning fuels comprising sulfur-containing combustible compounds and sorbent admixtures are also provided.
