Vacuum residuum and vacuum gas oil desulfurization
Abstract
Abstract A PROCESS FOR TREATING HEAVY HYDROCARBON FEEDSTOCK INTO A VACDISCLOSED COMPRISING SEPARATING THE FEEDSTOCK INTO A VACUUM GAS OIL FRACTION HAVING AN END BOILING POINT OF FROM ABOUT 1000*F. TO ABOUT 1200*F. AND A VACUUM RESIDUUM (VR) FRACTION. THE VACUUM GAS OIL (VGO) FRACTION IS CONTACTED AT A TEMPERATURE IN THE RANGE OF FROM 650*F. TO 850*F. AND A PRESSURE FO FROM 1200 LIQUID HOURLY SPACE VELOCITY OF FROM 1.0 TO 4.0, WITH A HYDRODESULFURIZATION CATALYST COMPRISED OF AT LEAST ONE HYDROGENATING COMPONENT SELECTED FROM GROUP VI METALS AND COMPOUNDS OF GROUP VI METALS AND AT LEAST ONE HYDROGENATING COMPONENT SELECTED FROM GROUP VIII METALS AND COMPOUNDS OF GROUP VIII METALS IN INTIMATE ASSOCIATION WITH AN ALUMINA CARRIER IN WHICH DISCRETE, SUBSTANTIALLY INSOLUBLE METAL PHOSPHATE PARTICLES ARE UNIFORMLY DISPERSED. THE VACUUM RESIDUUM FRACTION CONTACTED WITH A HYDRODESULFURIZATION CATALYST AT A TEMPERATURE FROM 650* TO 850* F., A PRESSURE OF FROM 800 TO 3000 P.S.I.G., AND A LIQUID HOURLY SPACE VELOCITY OF FROM 0.1 TO 1.5, WITH SAID HYDRODESULFURIZATION CATALYST HAVING THE SAME COMPOSITION AS THE CATALYST USED TO DESULFURIZE THE VGO.
