Abstract

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.

First claim

The invention claimed is:

1. A hydroprocessing apparatus, comprising:
A) a vacuum distillation column;
B) a hydroprocessing reactor, comprising:
1) a first bed;
2) a second bed; and
3) 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; and
2) 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.

2. The hydroprocessing apparatus according to claim 1 , wherein the plurality of lines further comprises a third line for withdrawing a third stream from a third location in the vacuum distillation column and communicating the third stream upstream of the first bed wherein the third location is at a lower elevation on the vacuum distillation column than the second location.
