    Abstract: An aviation gasoline (Avgas) formulation free from tetraethyl lead (TEL) for piston driven aircraft is described, the formulation comprising, in volume percent, between 0 and 65.2 base alkylate, between 0 and 50 super-alkylate, between 0 and 25 toluene, between 2 and 10 of a toluidine isomer blend, between 0 and 5 ethyl alcohol, between 0 and 25 C5 cut and between 0 and 10 triptane. The formulations are prepared by admixing the components, with the order of mixing being from the denser to the less dense, except in the case of the toluidine isomer blend, which in spite of being the denser product is the latest to be added to the other streams in order to by-pass homogenization problems.

  • Patent number: 7837747
    Abstract: This invention disclosure describes a conditioned single phase hydrocarbon-based fuel, a method for producing such fuel and components useful in such method. The described conditioned hydrocarbon-based fuel is a single phase hydrous fuel with improved performance, handling and storage characteristics. A method is also is also provided for producing the conditioned hydrocarbon-based fuel using a semi-solid activator. The resulting conditioned hydrocarbon-based fuel has a volume greater than the unmodified hydrocarbon-based fuel, a BTU content greater than the BTU content of the unmodified hydrocarbon-based fuel, less particulate emissions and less non-particulate emissions than the unmodified hydrocarbon-based fuel, and a water content less than the water content of the unmodified hydrocarbon-based fuel.
