Gum and deposit formation from jet turbine and diesel fuels
The present paper describes measurements of rates of oxidation and soluble gum formation in both pure hydrocarbons and in mixed hydrocarbon fuels. Some patterns which appear can be explained on the basis of what is known about co-oxidation of hydrocarbon mixtures. The oxidations were conducted in an oil bath at 130/sup 0/C. Gum formation is closely associated with oxidation. The compounds that copolymerize with oxygen to produce polyperoxides require the least amount of oxygen to yield a mg of gum; among other pure hydrocarbons and fuels, the rates of gum formation and oxygen absorption decrease together. The most useful approach to understanding and reducing gum and deposit formation will come through understanding the effects of condensed aromatic and heterocyclic compounds on the oxidation rates of fuels. 4 figures. 4 tables.
