Abstract : The object of these studies is to develop an understanding of the effect of jet fuel hydrocarbon composition on the deposit formation process. Results to date indicate that olefins have a major effect on the rate of deposit formation. The addition of 10% 1-hexadecene to hexadecane increased the rate of deposit formation by a factor of 7, while the addition of 10% indene to decane increased the rate by a factor of 32. Other studies with series of pure normal paraffins indicated that the rate of deposit formation decreased with increasing carbon number. Studies on the addition of homogeneous metal complexes to jet fuels have been continued. The rate of deposit formation was found to be a function of the square root of the metal level; thus, metals catalyze the initiation reactions in the complex deposit formation process. The addition of several vanadium containing complexes to jet fuel also markedly increased the rate of deposit formation.
