Abstract
A fuel composition comprises at least a tetramethylcyclohexane having a quaternary carbon atom in the cyclohexane ring and optionally, a fuel component. The tetramethylcyclohexane 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 component selected from a diesel fuel, jet fuel, kerosene or gasoline. Methods of making and using the fuel composition are also disclosed.
Claims20
A fuel composition comprising a petroleum-based fuel component and at least one tetramethylcyclohexane having a quaternary carbon atom in the cyclohexane ring, wherein the amount of the tetramethylcyclohexane is at least about 1 wt. %, based on the total weight of the fuel composition.
A method of making a fuel composition comprising the step of contacting pinene with hydrogen in the presence of a hydrogenation catalyst to form at least one tetramethylcyclohexane having a quaternary carbon atom in the cyclohexane ring;
- and mixing the tetramethylcyclohexane with a fuel component to make the fuel composition.
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 at least one tetramethylcyclohexane having a quaternary carbon atom in the cyclohexane ring, and wherein the fuel composition is used to power the internal combustion engine.
