Abstract
A fuel composition comprises farnesane and/or farnesane derivatives and a conventional fuel component selected from diesel fuel, jet fuel, kerosene or gasoline. The farnesane or farnesane derivative can be used as a fuel component or as a fuel additive in the fuel composition. The fuel composition may further comprise a conventional fuel additive. Methods of making and using the fuel composition are also disclosed.
Claims20
A fuel composition comprising or obtainable from a mixture comprising:
- (a) an isoprenoid compound having the formula:
- or a stereoisomer thereof, wherein Z is H, O—R, or O—C(═O)R;
- and R is H, alkyl, cycloalkyl, aryl, alkaryl, or aralkyl;
- (b) a petroleum-based fuel;
- and
- (c) a fuel additive,
- wherein the amount of the isoprenoid compound is at least about 5 vol.% and the amount of the petroleum-based fuel is at least about 5 vol. %, both amounts based on the total volume of the fuel composition, and wherein the fuel composition has a flash point equal to or greater than 38° C. and has an initial boiling point between about 100° C. and about 200° C.
A method of making a fuel composition comprising obtaining a petroleum distillate and adding an isoprenoid compound having the formula
- and a fuel additive thereto, wherein Z is H, O—R, or O—C(═O)R;
- and R is H, alkyl, cycloalkyl, aryl, alkaryl, or aralkyl, wherein the amount of the petroleum distillate is at least about 5 vol. % and the amount of the isoprenoid compound is at least about 5 vol. %, both amounts based on the total volume of the fuel composition, and wherein the fuel composition has a flash point equal to or greater than 38° C. and has an initial boiling point between about 100° C. and about 200° C.
A vehicle comprising an internal combustion engine, a fuel tank connected to the internal combustion engine, and a fuel composition in the fuel tank, wherein the fuel composition comprises:
- (a) isoprenoid compound having the formula
- or a stereoisomer thereof,
- wherein Z is H, O—R, or O—C(═O)R,;
- and R is H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl;
- (b) a petroleum-based fuel;
- and
- (c) a fuel additive,
- wherein the amount of the isoprenoid compound is at least about 5 vol. % and the amount of the petroleum-based fuel is at least about 5 vol. %, both amounts based on the total volume of the fuel composition, and wherein the fuel composition has a flash point equal to or greater than 38° C. and has an initial boiling point from about 100° C. to 200° C., and wherein the fuel composition is used to power the internal combustion engine.
