Coal liquefaction process research. Quarterly report, April 1-June 30, 1983

Technical Report ·
OSTI ID:5633378
This quarterly report for the period April through June 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. 1 reference, 17 figures, 7 tables.
