Method for reducing sox emissions during the combustion of sulfur-containing combustible compositions

An improved method for reducing SOX emissions during combustion of a sulfur-containing hydrocarbon wherein the improvement comprises the precombustion steps of:

• a. emulsifying the hydrocarbon in water to form a preatomized fuel, and
• b. adding to said preatomized fuel 0.5-25% by weight of an admixture of 80.99.5.% by weight insoluble sulfur sorbent and 0.5-20% soluble sulfur sorbent.

A clean-burning fuel which produces low SOX emissions when burned which comprises a sulfur-containing combustible material and 0.5-25% by weight admixture of 80.99.5% by weight insoluble sulfur sorbent and 0.5-20% by weight soluble sulfur sorbent.

A clean-burning fuel which produces low SOX emissions when burned, comprising a preatomized fuel, formed from a viscous sulfur-containing hydrocarbon and 0.5-25% by weight admixture of 80.99.5% by weight insoluble sulfur sorbent and 0.5-20% by weight soluble sulfur sorbent.

A clean-burning fuel which produces low SOX emissions when burned which comprises

• a. about 90 to about 99% of a combustible preatomized fuel formed by emulsifying a vacuum bottom resid with water in a 70/30 ratio using 0.125% heteropolysaccharide biopolymer S-194 produced by Alcaligenes sp. ATCC 31961 and 1/250 parts oil of a surfactant package comprising 47.24% polyoxypropylene-polyoxyethylene block copolymer in prill form having a hydrophilic-lipophilic balance of about 30.5, 21.38% nonylphenol polyethylene glycol ether having an average molecular weight of 1980 amu, 21.38% dinonylphenol ethoxylate having an average molecular weight of 6900 amu and 10% purified free acid pine lignin;
• and
• b. about 1 to about 10% of an admixture comprising about 90 to about 99% CaCO.sub.3 and about 1 to about 10% Na.sub.2 CO.sub.3.
