Hydrodesulfurization process with catalysts whose pore sizes are concentrated in a narrow range

Abstract

Abstract A PROCESS FOR THE DYDRODESULFURIZATION OF A CRUDE OIL, A REDUCED CRUDE OIL OR A HEAVY GAS OIL COMPRISING PASSING SAID OIL AND HYDROGEN OVER A CATALYST COMPRISING SUPPORTED GROUP VI AND GROUP VIII METALS. THE CATALYST HAS A PORE VOLUME OF AT LEAST 0.40 CC./GRAM WITH AT LEAST 65 PERCENT OF THE PORE VOLUME INCLUDED WITHIN A RELATIVELY NARROW PORE SIZE RANGE AS DETERMINED BY ISOTHERMAL NITROGEN DESORPTION MEASUREMENT AT LIQUID NITROGEN TEMPERATURES. THE ISOTHERMAL NITROGEN DESORPTION GRAPH FOR THE CATALYST SHOWS THAT THE CHANGE OF VOLUME OF NITROGEN IN THE CATALYST PER UNIT CHANGE IN PORE RADIUS VERSUS INCREASING PORE RADII WITHIN SAID NARROW PORE SIZE RANGE EXHIBITS AT LEAST ONE PEAK FROM WHICH THE CURVE DESCENDS AND DURING ITS DESCENT IT REVERSES DIRECTION LAND REASCENDS, WITH A DESCENT AND REASCENT MAGNITUDE OF AT LEAST 0.001 MILLILITERS PER GRAM PER ANGSTROM UNIT, TO FORM AT LEAST ONE OTHER PEAK WITHIN SAID NARROW PORE SIZE RANGE.
