In conclusion, it may be stated that: Recycle processing of SRC-I coal extract produced an equilibrium recycle solvent containing 9 weight percent hydrogen after two recycle passes in the PDU; no refractory 850/sup 0/F+ material was detected when recycling 500/sup 0/F+ material; an 850/sup 0/F+ conversion of approximatly 87 weight percent (based on fresh SRC-I feed) was obtained during recycle processing at temperatures of 790 to 810/sup 0/F; a distillate product (390 to 850/sup 0/F) containing < 0.3 weight percent nitrogen was routinely obtained during recycle processing at the above noted high conversion; and in the recycle mode of processing coal extract at 780/sup 0/F, a catalyst addition rate of one pound of catalyst per ton of moisture-free coal gave an 850/sup 0/F+ conversion of 62 weight percent (based on fresh SRC-I feed) and a nitrogen content in the distillate fraction (390 to 850/sup 0/F) of 0.36 weight percent.
