  • Anti-static additive compositions for hydrocarbon fuels
    Publication number: 20040107635
    Abstract: It has been discovered that less expensive, and in some cases synergistically effective anti-static additive blends may be added to hydrocarbon fuels to improve the conductivity thereof. The blend includes an anti-static amount of at least one hydrocarbon soluble copolymer of an alkylvinyl monomer and a cationic vinyl monomer and an anti-static amount of at least one hydrocarbon soluble polysulfone copolymer of at least one olefin and sulfur dioxide. Optional ingredients include polymeric polyamines and aryl sulfonic acids.

  • Composition
    Publication number: 20030000131
    Abstract: The present invention provides a composition comprising (i) an aviation fuel; and (ii) a deposit inhibiting compound of the formula P-Q-R in which P is a polymeric hydrocarbyl group in which Q is an optional ring system; in which R is a group selected from H and hydrocarbyl; wherein if R is a hydrocarbyl group it is free of a carboxylic acid group (—COOH); wherein Q together with R contains no greater than 2 nitrogens; and wherein when Q together with R contains 2 nitrogens each of the nitrogens is a member of a heterocyclic ring
