    Abstract: 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.

    Abstract: A method is provided for reducing the nitrogen oxide content of a flue gas produced by the combustion of fuel by introducing a nitrogen oxide removal agent into either the nitrogen oxide contaminated flue gas or the fuel to be combusted. The nitrogen oxide removal agent is the reaction product of a carbon compound in a pyrolysis liquor and a nitrogen compound such as ammonia, ammonium hydroxide or urea. The carbon compound is selected from carboxylic acids, phenols, esters, aldehydes and ketones. The pyrolysis liquor is derived from a feed stock containing cellulose, lignin or starch.
