This program is limited to research on upgrading coal liquid products from existing coal liquefaction processes to clean distillate fuels by catalytic hydrogenation at elevated temperatures and pressures. Samples of the products from PAMCO, H-Oil, COED and SYNTHOIL are heated and pumped, with and without solvent, into a catalytic reactor in the presence of hydrogen and other reducing gases. Variables being investigated include temperature, pressure, space velocity, hydrogen-to-oil ratio, and chemical nature of the solvent. The catalysts studied include nickel molybdate and sulfide, nickel tungstate and other combinations on carriers such as mordanites and other molecular sieve types. Almost 50 catalytic experiments were run with samples of COED tar, SYNTHOIL and SRC products and evaluated with respect to percentage of products boiling below 700/sup 0/F, denitrogenation and desulfurization.
