This quarterly report presents a literature review of the importance of diffusional effects in the hydroprocessing of coal liquids, as well as some experimental work done in this area using a model compound system, naphthalene hydrogenation. The literature review (Section I of this report) is of importance in all tasks of the contract. The ultimate goal of this contract is to obtain an improved catalyst for coal processing. One way of improving currently used catalysts is to minimize or eliminate the diffusional resistance now encountered by large coal derived molecules and to enhance the accessibility of the active catalytic agent on the surface. Other facets of this contract are concerned with improvement of the active catalytic agent itself. Section II of this report deals with experimental work on catalyst selection, refinement, tailoring using model compound and coal conversion studies. Work has begun with a simple model compound system, naphthalene hydrogenation, in the presence of a commercial CoMo/Al/sub 2/O/sub 3/ catalyst. Experiments are in progress to ascertain the role of diffusion in determining the overall catalytic reaction rate with this catalyst. 9 references, 7 tables.
