摘要

One exemplary embodiment can be a process for hydroprocessing. The process can include providing a hydroprocessing zone having at least two beds, and quenching downstream of a first bed of the at least two beds with a first vacuum gas oil that may be lighter than another vacuum gas oil fed to the first bed.

主权项

1. A hydroprocessing apparatus, comprising:
A) a vacuum distillation column; B) a hydroprocessing reactor, comprising:
1) a first bed;2) a second bed; and3) a third bed; and C) a plurality of lines, comprising:
1) a first line for withdrawing a first stream from a first location in the vacuum distillation column and communicating the first stream downstream of the first bed; and2) a second line for withdrawing a second stream from a second location in the vacuum distillation column and communicating the second stream downstream of the second bed; wherein the first location is at a lower elevation on the vacuum distillation column than the second location.
