This quarterly report for the period July through September 1983 summarizes activities in Sandia National Laboratories' continuing program of research on direct coal liquefaction. The program, composed of two projects - Advanced Concepts for Multistage Coal Liquefaction and Catalyst Studies in Coal Liquefaction - has as its overall goals to provide an understanding of the mechanisms and kinetics of primary and secondary reactions in coal liquefaction; to explore advanced concepts for multistage processing; and to determine the effect of process variables on catalyst deactivation. During this period, work was performed on: microreactor experiments with Wyodak coal and model solvents (with hydrogen donor and/or basic nitrogen properties) to study the role of hydrogen bonding in dissolution of subbituminous coals; continued testing of the continuous flow reactor for determination of catalyst deactivation; construction and testing of a high pressure model compound testing unit; definition of a model which accurately represents the heterogeneous catalytic hydrogenation of pyrene; microreactor experiments to explore the role of hydropyrenes as sources of hydrogen in hydrogenolysis; kinetics of the dissolution of Kentucky No. 9 coal in phenanthrene at 320/sup 0/C in the atmospheric ebullated coal bed/solvent extraction apparatus; determination of metal concentrations, surface areas and pore volumes of catalyst samples from Wilsonville; determination of cracking, hydrodesulfurization and hydrogenation activities of catalyst samples from the Integrated Two Stage Liquefaction pilot plant; and shakedown of the atmospheric model compound testing unit. 10 references, 16 figures, 5 tables.
