Abstract 1. A PROCESS FOR DESULFURIZING COAL COMPRISING PASSING A FLUID STREAM OF THE COAL IN A LIQUID SLURRY THROUGH A REACTOR CONTAINING AN IMMOBILIZED BED OF CATALYST PARTICLES, SAID BED HAVING AN INTERSTITIAL VOID SPACE OF ABOUT 20-80% AND SAID CATALYST BEING A DESULFURIZATION CATALYST FROM THE GROUP CONSISTING OF A COBALT MOLYBDATE SUPPORTED ON ALUMINA, SILICASTABILIZED COBALT MOLYBDATE SUPPORTED ON ALUMINA AND NICKEL MOLYBDATE SUPPORTED ON ALUMINA, WHEREIN SAID STREAM IS PASSED TO AND THROUGH SAID BED AT A RATE OF ABOUT 50 TO 1000 POUNDS PER HOUR PER CUBIC FOOT OF VOID SPACE IN SAID BED; WHEREIN THE REACTION CONDITIONS IN THE BED ARE ABOUT 300-500*C. AND 500-40,000 P.S.I.G.; SIMULTANEOUSLY PASSING A REDUCING GAS THROUGH SAID BED, SAID REDUCING GAS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, CARBON MONOXIDE, STEAM AND MIXTURES THEREOF, SAID GAS FLOW RATE BEING ABOUT 10-2000 S.C.F./ POUND OF SAID STREAM AND AT A VELOCITY SUBSTANTIALLY ABOVE TURBULENT FLOW, THE MODIFIED REYNOLD''S NUMBER, NRE'' OF SAID GAS FLOW RATE BEING AT LEAST 100; AND REMOVING A LIQUID FUEL OIL PRODUCT FROM SAID REACTOR.
