Abstract
Improved catalyst supports, supported catalyst, and method of preparing and using the catalysts for the hydrodesulfurization of a residuum hydrocarbon feedstock are disclosed. The catalyst supports comprise titania alumina having 5 wt % or less titania and have greater than 70% of their pore volume in pores having a diameter between 70 Å and 130 Å and less than 2% in pores having a diameter above 1000 Å. Catalysts prepared from the supports contain Groups 6, 9 and 10 metals or metal compounds, and optionally phosphorus, supported on the titania alumina supports. Catalysts in accordance with the invention exhibit improved sulfur and MCR conversion in hydrotreating processes.
