METHOD FOR TREATING HYDROPROCESSING CATALYSTS WITH AN ORTHOPHTHALATE AND SULPHURATION METHOD USING THE SAME

Document Type and Number:

WIPO Patent Application WO2004091789

Kind Code:

A8

Abstract:

The invention relates to a method for impregnating a hydroprocessing metal catalyst in the oxide form with at least one orthophthalate, either dissolved or dispersed in a liquid. The invention further relates to a method for sulphuration of a hydroprocessing metal catalyst in the oxide form, comprising a) an impregnation step as above followed by b) a step for bringing the catalyst treated thus into contact with a sulphuration agent and c) a step for bringing into contact with hydrogen, where step b) is followed by step c) or steps b) and c) are carried out simultaneously.
