Hydrodesulfurization with expanded or moving bed of catalyst having specific particle diameter and specific pore diameter
Abstract
Abstract A PROCESS FOR CATALYTICALLY HYDRODESULFURIZING RESIDUAL HYDROCARBON OILS HAVING A TOTAL VANADIUM AND NICKEL CONTENT ABOVE 30 P.P.M.W. AND A C5-ASPHALTENE CONTENT ABOVE 0.5% WT., WITH CATALYST REPLENISHMENT DURING OPERATION, WHICH INCLUDES PASSING THE RESIDUAL OIL TOGETHER WITH HYDROGEN THROUGH CATALYST PARTICLES IN THE FORM OF A SUSPENSION OR EXPANDED BED HAVING HYDRODESULFURIZATION ACTIVITY AT HYDRODESULFURIZATION REACTION CONDITIONS, THE CATALYST PARTICLES IN SAID BED HAVING A PORE VOLUME ABOVE 0.3 ML.?G., LESS THAN 10% OF THE PORE VOLUME BEING PRESENT IN PORES HAVING A DIAMETER ABOVE 1000 A., AND HAVING A SPECIFIC PORE DIAMETER, EXPRESSED IN A., OF FROM 45XD0.6 TO 140XD0.6 WHERE D IS THE SPECIFIC PARTICLE DIAMETER IN MM.
