ABSTRACT:
A process for producing ultra clean distillate and naphtha products wherein a distillate boiling range stream which contains heteroatoms and aromatics to subjected to three stage processing. The first stage is conventional hydrotreating, wherein the resulting effluent is further hydrotreated, but with a noble metal zeolite catalyst which is typically used for hydrocracking. The effluent from this second stage, which is now substantially free of heteroatoms, is passed to a third stage. This third stage is a hydrocracking stage, the severity of which will determine if the ultimate product will be a distillate or a naphtha.
