摘要
The present invention relates to a process for presulfiding hydrocarbon processing catalysts by impregnating the catalyst with an inorganic polysulfide solution containing at least one water-soluble oxygenated hydrocarbon such that at least a portion of said sulfide or sulfur is incorporated in the pores of said catalyst, and thereafter heating the sulfur-incorporated catalyst under non-oxidizing conditions to fix the incorporated sulfur onto the catalyst.
