The aim of the proposed research is to synthesize and investigate new sulfided catalyst systems having higher carbon-heteroatom hydrogenolysis activity as compared to ring hydrogenation activity. A fundamental approach is planned to gain understanding of the basic catalytic properties which relate to hydrogenolysis, hydrogenation and cracking functions of the catalysis. This will involve preparation of new catalysts, characterization of their properties and model compound reactivity studies. In another part of the project, selected catalysts will be applied in studies of more complex O- and N- containing model compounds with the objective of providing fundamental data on the stereochemistry of HDO and HDN reactions. These data will be used to develop steric surface-reactant models for sulfided catalysts. The research is divided into four tasks: A-catalyst preparation and activity testing; B-catalyst characterization; C-study of catalyst activity and functional selectivity under hydroprocessing conditions; and D-stereochemical studies. Two series of Al/sub 2/O/sub 3/-supported Ru, Rh, Pd and Re catalysts were prepared. In one of the series a high concentration, viz., 7.72 x 10/sup -2/ g atom of the noble metal/100 g of ..gamma..-Al/sub 2/O/sub 3/ was used, whereas in the second series the level of the noble metal was reduced to 1/8 of this concentration. The catalysts were subjected to activity and functional selectivity studies under Task C, and to stereochemical studies under Task D. Characterization studies under Task B are in progress. 1 figure, 4 tables.
