Abstract
This invention relates to a process for activating a hydroprocessing catalyst. More particularly, hydroprocessing catalysts are activated in the presence of carbon monoxide. The catalysts that have been activated by CO treatment have improved activity.
Claims20
A process for activating a metal-containing hydroprocessing catalyst which comprises:
- treating a fresh metal-containing hydroprocessing catalyst or a regenerated metal-containing hydroprocessing catalyst with carbon monoxide under catalyst activation conditions.
A process for activating a metal-containing hydroprocessing catalyst which comprises:
- (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.
