    摘要: A process for hydrodesulfurization of an asphaltic oil in the presence of a catalyst comprising Group VI and Group VIII metals on alumina in two stages in series wherein a greater quantity of catalyst is required in the second stage than in the first stage. Ammonia is added to the second stage to tend to equalize the amount of catalyst and the space velocity in each stage.

    摘要: A multiple stage process is described for the catalytic hydrodesulfurization and hydrodemetallization of a residual petroleum oil boiling above the gasoline range. The product of the process comprises essentially material boiling above the gasoline range and comprises little material boiling below the initial boiling point of the residual oil feed. The hydrodesulfurization-demetallization process comprises an initial stage involving relatively high hydrogen pressure in the presence of a catalyst comprising a relatively low proportion of catalytically active hydrogenation metals. The process employs a final stage in series having a relatively lower hydrogen pressure and a catalyst comprising a relatively higher proportion of hydrogenation metals. The stream entering the final stage contains an amount up to 10, 20 or even 25 weight percent of the asphaltene content of the charge to the first stage while the effluent from the final stage is essentially free of asphaltenes.

The product of the process comprises essentially material boiling above the gasoline range and comprises little material boiling below the initial boiling point of the residual oil feed. The hydrodesulfurization-demetallization process comprises an initial stage involving relatively high hydrogen pressure in the presence of a catalyst comprising a relatively low proportion of catalytically active hydrogenation metals in which demetallization activity is high with an unaged catalyst but diminishes as the catalyst becomes aged. The process employs a final stage in series having a relatively lower hydrogen pressure and a catalyst comprising a relatively higher proportion of hydrogenation metals in which the demetallization activity is lower with an unaged catalyst but increases as the catalyst becomes aged. The stream entering the final stage contains an amount up to 10, 20 or even 25 weight percent of the asphaltene content of the charge to the first stage while the effluent from the final stage is essentially free of asphaltenes.

    摘要: A PROCESS FOR HYDRODESULFURIZING A CRUDE OIL OR A RESIDUAL OIL COMPRISES PASSING THE OIL AND HYDROGEN OVER AN HDS CATALYST, WITH THE HDS CATALYST CYCLE BEING LIMITED BY THE MAXIMUM TEMPERATURE THAT THE REACTOR METALS CAN WITHSTAND AT THE PROCESS PRESSURE. AS THE HYDRODESULFURIZATION PROCEEDS, METALS FROM THE FEED OIL ARE DEPOSITED ON THE CATALYST UNTIL MAXIMUM POSSIBLE METALS LOADING ON THE CATALYST IS REACHED. AS THE PROCESS PROCEEDS, A CONTINUAL TEMPERATURE RISE IS REQUIRED TO ACHIEVE THE REQUIRED SULFUR REMOVAL UNTIL THE MAXIMUM OR CONSTRAINT TEMPERATURE IS REACHED. ACCORDING TO THIS INVENTION, IT HAS BEEN FOUND THAT BY MAINTAINING THE SPACE VELOCITY AT A SUFFICIENTLY LOW VALUE THE CATALYST EXPERIENCES MAXIMUM METALS LOADING BEFORE THE CONSTRAINT TEMPERATURE IS REACHED SO THAT FULL CATALYST LIFE IS UTILIZED.

    摘要: A fluid catalytic cracking system in which hydrocarbon feed and a zeolite catalyst or a catalyst of comparable activity and/or selectivity to gasoline is charged to a reactor having a short residence time is improved by charging only a portion of the fresh or freshly regenerated catalyst which is used to the inlet of the reactor together with the hydrocarbon feed and charging the remainder of the freshly regenerated catalyst substantially without hydrocarbon feed downstream in the reactor. This arrangement results in a higher gasoline yield and a higher selectivity to gasoline in the reactor.
