Process for sulfurization of hydrogenation catalysts

摘要

A process for activating a hydrogenation catalyst in a hydrogenation system having multiple reaction stages by sulfurization comprising sulfurizing the hydrogenation catalyst in each reaction stage with a sulfur-containing hydrocarbon oil and a hydrogen-rich gas containing less than 1000 ppm (by volume) of hydrogen sulfide, successively in the order of from the final reaction stage thereof to the first reaction stage thereof.
