Catalytic hydrogenation of Pittsburg and Midway Coal Mining Company's Solvent Refined Coal was accomplished using commercial hydrotreating catalysts and hydrotreating catalysts fabricated at Montana State University. Forty-four batch autoclave tests and thirty-nine trickle bed reactor tests were performed. Liquid products from the catalyst tests were analyzed for sulfur content, nitrogen content, and distillate yields. Harshaw HT-400 E 1/16'' (Co--Mo) catalyst gave the best nitrogen removal at 450/sup 0/C of all commercial catalysts tested in the trickle bed reactor. Cyanamid HDS-20A 1/16'' Trilobe (Co--Mo) gave the best sulfur removal at 450/sup 0/C of all catalysts tested in the trickle bed reactor. MSU STK-5-2-2-1.5E (Ni--Co--Mo) gave the best nitrogen removal at 450/sup 0/C of all catalysts tested. MSU STK-5-2-6-1.5E (Ni--Co--Mo) gave the best sulfur removal at 450/sup 0/C of all catalysts tested. A metal loading study was performed to determine the effects of nickel oxide, cobalt oxide, and molybdenum trioxide concentrations on heteroatom removal. Increased molybdenum trioxide concentration significantly improved nitrogen removal. Increased nickel oxide and cobalt oxide concentrations also improved nitrogen removal.
