Research and development of an advanced process for the conversion of coal to synthetic gasoline and other distillate fuels. Quarterly progress report No. 3, November 1976--January 1977. [CoO-MoO/sub 3/

Abstract

It is concluded that: The Sun catalyst, 1 percent CoO-2 percent MoO/sub 3/ on granular bauxite is as active as the best previously tested catalyst, Filtrol HPC-5. The Sun catalyst causes less cracking and less formation of methane. Its use thus results in a more efficient utilization of hydrogen. The Sun catalyst apparently promotes the formation of a larger proportion of basic nitrogen in the total nitrogen remaining in the liquid product. This should result in a more efficient removal of nitrogen from the product by treatment with hydrogen chloride. Hydrogenated anthracene oil is preferable to non-hydrogenated anthracene oil as a solvent for the dissolution and hydrogenation of Illinois No. 6 coal. Hydrogenated anthracene oil provides a greater depth of hydrogenation of the coal-derived liquid portion of the product. Stripped solvent-refined coal filter feed can be hydrogenated successfully but subsequent solids removal may be a problem. Sufficient data have been obtained concerning rates of hydrogenation, product characteristics, etc., to undertake design of 1-3 lb/hr. continuous, bench-scale hydrogenation unit. A stirred tank reactor is preferable to a plug flow tube reactor for the 1-3 lb/hr continuous bench-scale unit.
