Abstract
Abstract A single catalyst system capable of demetalizing, hydrotreating and hydrodewaxing petroleum residue in a single stage process is described. The catalyst system utilized includes one or more metal oxides or sulfides of Group VIA and Group VIII of the periodic Table impregnated on a base of refractory oxide material and Zeolite Beta. The catalyst also has about 75% of its pore volume in pores no greater than 100 Angstrom units in diameter and about 20% of its pore volume in pore greater than about 300 Angstrom units in diameter.
