Claims
- 1. 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.
- 2. A composition as recited in claim 1 wherein said nanotubes are substantially cylindrical, graphitic carbon nanotubes of substantially constant diameter less than 0.1μ, comprise cylindrical graphitic sheets whose c-axes are substantially perpendicular to their cylindrical axis, are substantially free of pyrolytically deposited carbon and have a length to diameter ratio from 5:1 to 500:1, said nanotubes being dispersed in said fuel.
- 3. A composition as recited in claim 1 wherein said nanotubes are substantially cylindrical, graphitic carbon nanotubes of substantially constant diameter less than 0.1μ, comprise cylindrical graphitic sheets whose c-axes are substantially perpendicular to their cylindrical axis, are substantially free of pyrolytically deposited carbon and have a length to diameter ratio from 5:1 to 500:1.
- 4. 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
