Catalytic hydrogenation of a three-component mixture of polyaromatic hydrocarbons in the presence of iron-containing additives

Abstract

The results of the catalytic hydrogenation of a three-component anthracene-benzothiophene-biphenyl mixture in the presence of different catalytic additives are given. It was found that the conversion of the mixture of model substances was 85.9 or 85.0% with the use of FeS2 or Fe2O3 + S (1 : 1), respectively; in both cases, hydrocracking was the prevailing reaction path. A comparatively small difference was found in the products of hydrogenation and hydroisomerization, which was related to the hydrogenation of the structure of each particular component.
