Abstract
This invention relates to a process for activating a hydroprocessing catalyst and the use of activated catalyst for hydroprocessing. More particularly, hydroprocessing catalysts are activated in the presence of carbon monoxide. The catalysts that have been activated by CO treatment have improved activity.
Claims35
A hydroprocessing process which comprises:
- contacting a feedstock with a hydroprocessing catalyst under hydroprocessing conditions wherein said hydroprocessing catalyst is a metal-containing hydroprocessing catalyst that has been activated by treating a fresh metal-containing hydroprocessing catalyst or a regenerated metal-containing hydroprocessing catalyst with carbon monoxide under catalyst activation conditions.
A hydroprocessing process which comprises:
- contacting a feedstock with a hydroprocessing catalyst under hydroprocessing conditions wherein said hydroprocessing catalyst is a metal-containing hydroprocessing catalyst that has been activated by (a) treating a fresh metal-containing hydroprocessing catalyst or a regenerated metal-containing hydroprocessing catalyst with a carbon monoxide precursor, and (b) contacting carbon monoxide precursor treated catalyst from step (a) with hydrogen and a sulfiding agent under catalyst activation conditions.
