Abstract: IN THE LIQUID PHASE CATALYTIC HYDROGENATION OF COAL, IMPROVED OPERATION IS OBTAINED BY INITIALLY PASSING THE PRESSURIZED AND PREHEATED COAL-OIL SLURRY CONTAINING RELATIVELY LARGE COAL PARTICLES THROUGH A PRETREATMENT REACTOR, WHEREIN THE COAL PARTICLES ARE PARTIALLY DISSOLVED TO PRODUCE FINE PARTICLES SO THAT A BETTER CONTROL OF EBULLATION CAN BE ACHEIVED IN THE FINAL UPFLOW CATALYTIC REACTOR.

Abstract: THE LIQUID PHASE CATALYTIC HYDROGENATION OF COAL TO LIQUID AND GAS PRODUCTS IS IMPROVED BY THE PRETREATMENT OF THE CATALYST WITH HYDROGEN, WHEREIN THE PRETREATMENT TEMPERATURES ARE LIMITED TO ABOUT 200-400*F. AND THE CATALYST IS SUBSTANTIALLY UNREDUCED BEFORE START-UP OIL IS INTRODUCED INTO THE REACTOR.

Abstract: IN THE HYDROCONVERSION OF CERTAIN PETROLEUM STOCKS, SUCH AS LLOYDMINSTER CRUDE MIXTURES FROM CANADIAN SOURCES, ACCEPTABLE DESULFURIZATION LEVELS CAN ONLY BE OBTAINED BY THE USE OF A DESULFURIZATION CATAYST OPERATING IN UPFLOW LIQUID PHASE IN ACCORDANCE WITH THE EBULLATED BED SYSTEM BY MAINTAINING A CONVERSION RATE SUCH THAT A MAXIMUM HEPTANE INSOLUBLE NUMBER OF 60 IS NOT EXCEEDED.
