Abstract
THE PRESENT INVENTION RELATES TO A PROCESS FOR HYDRO-STABILIZING A COAL LIQUEFIED OIL, CHARACTERIZED IN FILTERING THE COAL LIQUEFIED OIL, FEEDING IT TO AN EXPANDED BED REACTOR (8), CONTACTING WITH HYDROGEN AND A HYDROREFINING CATALYST THEREIN TO HYDROREFINE THE COAL LIQUEFIED OIL, THEN GAS-LIQUID SEPARATING, FRACTIONATING THE REACTOR EFFLUENT TO OBTAIN A HYDROSTABILIZED PRODUCT OF THE COAL LIQUEFIED OIL. AN EXPANDED BED REACTOR (8) IS USED IN THE PROCESS EFFECTIVELY ALLEVIATES THE PROBLEM ASSOCIATED WITH THE RAPID INCREASE OF PRESSURE DROP IN THE REACTOR (8), INHIBITS THE UNDESIRED RAPID DEACTIVATION OF THE CATALYST AT THE INLET OF THE REACTION, AND PROLONGS THE ON-STREAM PERIOD. IN ADDITION, IT CAN REMOVE NITROGEN AND OXYGEN FROM THE COAL LIQUEFIED OIL, AND IMPROVE THE QUALITY THEREOF.
