A process for simultaneously hydrotreating and dewaxing petroleum fractions is described. The process utilizes a single catalyst system which includes a hydrotreating component impregnated on a controlled pore size base and at least two catalyst components selected from any of an intermediate pore zeolite, a large pore zeolite or Zeolite Beta, and a large pore non-zeolite catalyst.

A process comprising the steps of simultaneous demetallating, hydrodesulfurizing and dewaxing petroleum residua at least 50% of which boils above 750°F. by contacting said residua with a catalyst, comprising: (a) a hydrogenation/dehydrogenation component supported on catalytically active alumina, sa

A process comprising the steps of simultaneous demetallating, hydrodesulfurizing and dewaxing petroleum residua at least 50% of which boils above 750°F. by contacting said residua with a catalyst, comprising: (a) a hydrogenation/dehydrogenation component supported on catalytically active alumina, said alumina having a controlled pore size whereby said catalyst has 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; and (b) an intermediate pore zeolite, and zeolite beta as a large pore component and a large pore non-zeolitic inorganic binder.
