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.

A catalytic composition comprising: a base component comprising 5-30 wt % Zeolite Beta and 95-70 wt % of an inorganic oxide material, based on the combined weight of said Zeolite Beta and the inorganic oxide material; and a hydrogenation/dehydrogenation component supported on the base component, sai

A catalytic composition comprising: a base component comprising 5-30 wt % Zeolite Beta and 95-70 wt % of an inorganic oxide material, based on the combined weight of said Zeolite Beta and the inorganic oxide material; and a hydrogenation/dehydrogenation component supported on the base component, said hydrogenation/dehydrogenation component comprising a catalytically effective amount of at least one metal selected from Group VIA and Group VIII of the Periodic Table, said catalyst having about 75% of its pore volume in pores no greater than 100 Angstrom units in diameter and about 20% of its pore volume in pores greater than about 300 Angstrom units in diameter.
