Abstract
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.
