It is the objective of this research to convert coal to clean distillate fuels. This program will be limited to research on products from existing coal liquefaction processes. The results of batch tests of COED tar with sixteen different hydrocracking catalysts are reported as well as that from three catalysts tested in the continuous reactor. In a typical result Harshaw's Ni-4401 catalyst removed 76 percent of the sulfur, 37 percent of the nitrogen and converted 79 percent of the feed to material boiling below 700/sup 0/F Three commercial and one laboratory catalyst were tested with SYNTHOIL in five batch runs and one continuous run. The ''best'' catalyst gave a 67 percent conversion to material boiling below 700/sup 0/F when hydrocracked at 450/sup 0/C and 800 psi. The results of batch tests with nine catalysts and continuous reactor tests with five different catalysts on SRC vacuum flash feed are reported. Shell's number 324E /sup 1///sub 16/'' catalyst removes 39 percent of the nitrogen, 71 percent of the sulfur and gives 77 percent conversion to material boiling below 700/sup 0/F The results of treating SRC with thirty different catalysts are reported. Conversions to liquid product boiling below 700/sup 0/F of 22--31 percent, desulfurization of 35--53 percent and denitrogenation of 28--35 percent were obtained.
