    Abstract: A process and catalyst that provides for the upgrading of a high endpoint gas oil feedstock that contains significant concentrations of organic sulfur compound and organic nitrogen compounds. Included among the sulfur compounds are the dimethyl-dibenzothiophenes and derivative thereof. The catalyst of the process is an additive impregnated composition or a derivative thereof that further comprises cobalt and molybdenum. The process provides for the upgrading the high endpoint gas oil feedstock by significantly reducing the difficult to remove thiophene and nitrogen compounds and the process does this with a significantly reduced hydrogen consumption relative to processes using comparative catalysts.

    Abstract: A low-pressure process for hydrodenitrogenation and hydrodesulfurization of a gas oil feedstock. The process uses a multi-bed, stacked-bed reactor system. The first and third beds of the multi-bed, stacked-bed reactor system include catalysts that comprise cobalt and molybdenum supported on alumina. The middle, second bed, includes a catalyst comprising nickel and molybdenum supported on alumina that preferably includes an additive. The stacked bed arrangement with the use of the specific catalysts provides for the low-pressure operation and significantly improved HDN and HDS activity with relatively insignificant differences in hydrogen consumption.
