ABSTRACT:
A method for activating a hydrodesulfurization catalyst by passing a gaseous stream comprising carbon oxides, hydrogen, and sulfur-containing compounds into contact with the catalyst at a temperature from about 400.degree. to about 700.degree. F. until the outlet gaseous stream from the catalyst has a sulfur content substantially equal to the sulfur content of the inlet gaseous stream and thereafter increasing the temperature incrementally and continuing to contact the catalyst with the inlet gas stream until the sulfur content in the outlet gaseous stream is substantially equal to the sulfur content of the inlet gaseous stream after each incremental temperature increase.
