Thesis/Dissertation ·
OSTI ID:6524654
Catalytic hydrogenation of Pittsburg and Midway Coal Mining Co.'s Solvent Refined Coal was carried out in 44 batch autoclave tests and 39 trickle-bed reactor tests by using commerical hydrotreating catalysts and catalysts fabricated at Montana State University Harshaw HT-400 E 1/16 in. (cobalt/molybdenum) catalyst gave the best nitrogen removal at 450/sup 0/C of all commercial catalysts tested in the trickle-bed reactor, and cyanamid HDS-20A 1/16 in. Trilobe (cobalt/molybdenum) gave the best sulfur removal. Of all the catalysts tested, MSU STK-5-2-2-1.5E (nickel/cobalt/molybdenum) and MSU STK-5-2-6-1.5E (nickel/cobalt) molybdenum gave the best nitrogen and sulfur removal at 450/sup 0/C, respectively. Increased molybdenum trioxide, nickel oxide, and cobalt oxide concentrations improved nitrogen removal.
