Process for the presulphurization of a hydrocarbon treatment catalyst |
abstract |
The invention relates to a process making it possible when a refining catalyst is subject preferably in situ to the conventional activation reaction in the presence of hydrogen (generally at above 100 DEG C.) to carry out, as a result of the in situ presence of hydrogen, the sulphurization at the required stoichiometric or non-stoichiometric level of the active metal or metals in the composition of the catalyst. In the absence of hydrogen, the process consists of incorporating into the porosity of the new or regenerated catalyst at least one sulphurizing agent of general formula: R-S(n)-R' in which n is an integer from 3 to 20 and R represents an organic radical. The invention is characterized in that a critical elementary sulphur quantity is added to the sulphurizing agent. This addition makes it possible to adjust the sulphur content of the presulphurized catalyst to values equal to or higher than stoichiometry, to increase the fixed sulphur quantity after activation under hydrogen and to reduce the exothermy phenomena observed during activation. |
