FUEL ADDITIVES USEFUL FOR REDUCING PARTICULATE EMISSIONS

摘要

A fuel for use in a jet engine may be prepared by admixing a hydrocarbon fuel and a first additive selected from the group consisting of ethoxylated alkylphenol formaldehyde resins, maleic anhydride alpha olefin copolymers and mixtures thereof and a second additive comprising an admixture of platinum group and cerium compounds. The jet fuels including the additives may be used in jet engines where it is desirable to have reduced concentrations of particulates in exhausts, particularly when the jet engines are running at cruise speed.
