Effective catalytic processing during direct liquefaction involves a number of physical interactions, two of which are catalytic reactions involving coal or solvent species, and thermal reactions of a coal-coal or a coal-solvent variety. In principle, slurry phase reaction schemes offer the possibility of accentuating the effects of catalysts by providing easy mutual access between coal, catalyst and solvent species when they first enter a heated reaction zone. Since one of the tasks of this study is to evaluate the performance of novel slurry phase catalysts, our efforts during this past quarter were in three areas relevant to this overall goal, namely: (1) preparation of supported and unsupported catalysts with high surface areas and minimal porosities, (2) enhancement and tailoring of the above materials to promote desired activities and selectivities, and (3) evaluation of the above noted materials using model compounds and coal systems to ascertain their performance thereby assisting in the preparation and tailoring of improved catalysts for further evaluations. 29 references, 26 figures, 14 tables.
