英文摘要	In support of the Pittsburgh Energy Research Center's SYNTHOIL Process for coal liquefaction, Sandia Laboratories has undertaken three tasks: Catalyst Improvement, Mineral Matter Effects, and Preheater Studies. In the last quarter, the catalyst improvement studies focused on the effects of nitrogen-containing compounds on the activity of presulfided cobalt molybdate catalyst pellets. Data from pulsed microreactor experiments have shown that pyridine, aniline, and pyrrole cause a decrease in the hydrodesulfurization of thiophene. In most cases these losses in activity were, to a great extent, reversible. In the mineral matter effects studies, chemical removal of pyrite and other mineral constituents has been carried out on Kentucky, West Virginia and Indiana coals. These coals were hydroliquefied in a batch autoclave. The viscosities and preasphaltene contents of the resulting liquid products were higher than those obtained from the original, untreated coals. The continuous reactor used for the preheater studies has been completed, and preliminary pressure testing has been started. The first shakedown run is expected in April.
