The objective of this project 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 applied to gain understanding of the basic catalytic properties which relate to hydrogenolysis and hydrogenation functions of the catalysts. This involves preparation of new catalysts, characterization of their properties, and model compound reactivity studies. Selected catalysts are applied in studies of more complex O- and N-containing model compounds with the objective of providing fundamental data on the stereochemistry of hydrogenation, HDO and HDN reactions. These data are used to develop steric surface-reactant models for sulfided catalysts. This knowledge could be reasonably expected to allow for tailoring of selective sulfided catalysts possessing augmented C-O and C-N hydrogenolysis activity. Such new catalysts should be of particular importance for upgrading of coal-derived liquids and solids, as well as other heavy feedstocks. Research is divided into four tasks: A--catalyst preparation and activity testing; B--catalyst characterization; C--catalyst activity and functional selectivity under hydroprocessing conditions; and D--stereochemical studies. Results are discussed. 30 refs., 15 figs., 16 tabs.
