A &component mixture simulating rapid &al pyrolysis‘&r was hydrogenated over different catal sts and temperatures to determine the degree of conversion of the indivi (rual components and the degree of removal of heteroatoms. Benzothiophene is 100% converted on all catalyst. The degree of hydrogenation of biphenyl was low; no conversion of dibenzofuran m the mixture was observed over all catalysts. Anisole was converted to a substantially larger degree than o-cresol; mtrogen was eliminated to a larger degree from quinoline than indole. 98104892
