Abstract
Improved fuel compositions containing carbon nanotubes in from 0.01% to 30.0% by weight of fuel have improved bum rate and other valuable properties. Improved lubricant compositions containing carbon nanotubes in from 0.01 to 20.0% by weight of lubricant have improved viscosity and other valuable properties.
Claims4
A liquid hydrocarbon fuel composition having improved fuel properties containing:
- (a) a petroleum derivative comprising gasoline, gas oil, kerosene, diesel fuel or heavy oil;
- and
- (b) carbon nanotubes in from about 0.1% to about 10.0% by weight of said fuel, said nanotubes having a diameter less than 0.5μ and a length to diameter ratio of at least 5.
A method of producing an improved fuel containing carbon nanotubes comprising the steps of:
- (a) forming a mixture of a polymeric matrix and carbon nanotubes, said mixture containing from about 1 to about 30% by weight of carbon nanotubes;
- and
- (b) combining the mixture formed in step (a) with a petroleum derivative comprising gasoline, gas oil, kerosene, diesel fuel or heavy oil, in such amount as to form a fuel having from about 0.1% to about 10.0% by weight of carbon nanotubes in said fuel. fuel selected from the group consisting a petroleun derivative fuel selected from the group consisting of gasoline, gas oil, kerosene, diesel fuel and heavy oil
