This quarterly report, for the period October 1-December 31, 1981, summarizes Sandia's activities in coal liquefaction process research. The overall objectives of the program are to understand the mechanisms of coal liquefaction, to determine the role of catalysts in the direct conversion of coal to liquids, to determine the mechanism of catalyst deactivation and to explore slurry phase catalyst systems. Specific projects include: short-contact-time coal liquefaction, mineral matter effects and catalyst studies. During this period, work was performed on: a study of the reactivities of asphaltenes and preasphaltenes prepared at 350 to 450/sup 0/C; the determination of rate constants for solvent hydrogenation under conditions of limited hydrogen availability; installation of a radiometric catalyst level detector at the H-Coal bench reactor facility (Trenton, NJ); exploratory evaluation of highly dispersed titanate catalysts; continued characterization of aged catalysts from H-Coal PDU runs No. 9 and 10; and the determination of the relationship between hexene and anthracene hydrogenation rates of aged catalysts and the surface properties of the catalyst. In addition, a novel shaking microreactor was designed, constructed and evaluated for carrying out coal liquefaction reactions under multistage processing conditions.
