It is the object of this research to convert coal to clean distillate fuels. This program will be limited to research on the product from existing coal liquefaction processes. Liquefied coal will be converted by a catalytic hydrogenation at elevated temperatures and pressures. Samples of the products from PAMCO, H-Oil, COED, and SYNTHOIL will be obtained. They will be heated and pumped, with and without solvent, into a catalytic reactor in the presence of hydrogen and other reducing gases. Variables to be investigated will include temperature, pressure, space velocity, hydrogen-to-oil ratio, chemical nature of the solvent. The catalysts to be studied will include nickel molybdate and sulfide, nickel tungstate, and other combinations on carriers such as mordanites and other molecular sieve types. Nineteen batch and seven continuous runs on SRC Vacuum Flash Feed are reported with denitrogenation up to 38 percent and desulfurization up to 75 percent achieved. On COED Pyrolysis Oil, eight batch and four continuous runs are reported with denitrogenation up to 45 percent and desulfurization up to 90 percent accomplished. Twenty-eight batch and nine continuous runs on SYNTHOIL are reported with denitrogenation up to 32 percent and desulfurization up to 48 percent attained. Shell's No. 344 cobalt molybdate catalyst gives 48 percent desulfurization, 32 percent denitrogenation, and 50 percent conversion to distillate material from SYNTHOIL. It gives 65 percent desulfurization and 30 percent denitrogenation with SRC and 88 percent desulfurization and 20 percent denitrogenation with FMC tar.
