Abstract

Catalyst supports, supported catalysts, and a method of preparing and using the catalysts for the demetallation of metal-containing heavy oil feedstocks are disclosed. The catalyst supports comprise alumina and 5 wt % or less titania. Catalyst prepared from the supports have at least 30 to 80 volume percent of its pore volume in pores having a diameter of between 200 and 500 angstroms. Catalysts in accordance with the invention exhibit improved catalytic activity and stability to remove metals from heavy feedstocks during a hydroconversion process. The catalysts also exhibit increased sulfur and MCR conversion.
