Process for presulfurizing a hydrogen treatment catalyst |
摘要 |
The invention concerns a process for sulfurizing a catalyst, particularly a refining catalyst comprising a carrier and active metal oxides. In a first step, a sulfur compound mainly consisting of organic polysulfide is introduced into the catalyst mass. A second step consists of first sulfurizing, in the absence of hydrogen, the active metal oxides at a temperature lower than 275 DEG C. and then activating the catalyst at a temperature higher than 275 DEG C. The present invention concerns a process for presulfurizing a hydrocarbon treatment catalyst and/or preconditioning a catalyst in view of subsequent presulfurization.
