Patent ID: 7541502

Claim:
A fuel composition for use in internal combustion engines, the fuel composition comprising: as a predominant component an organic distillate comprising hydrocarbon compounds boiling in a temperature range of from about 30° C. to about 230° C.; and a low-boiling, low-sulfur fraction from distillation of an alkylated petroleum feedstock consisting of material boiling between about 60° C. and about 345° C., wherein the alkylated petroleum distillate comprises one or more aromatic compounds represented by the formula where Ar is an aryl moiety of 6 or 7 carbon atoms, R is hydrogen or an alkyl group of 1 or 2 carbon atoms, and R′ and R″ are each an independently selected alkyl group of from 1 to 4 carbon atoms, and wherein the tow-boiling, low-sulfur fraction has a final boiling point of less than about 110° C. as measured by ASTM D86, and contains less than 50 ppm sulfur, wherein the fuel composition comprises aromatic compounds at a total concentration of up to about 35 percent by volume and the aromatic compounds represented by the above formula are at a concentration of from about 0.01 to about 20 percent by weight of the aforesaid total concentration of aromatic compounds.
