| 摘要 |
<p>The invention provides a process for presulphurizing porous particles of a sulphidable catalyst containing at least one metal or metal oxide, which comprises: (a) impregnating the catalyst with an inorganic polysulphide solution and at least one water-soluble oxygenated hydrocarbon to obtain a sulphur-incorporated catalyst in which at least a portion of the sulphide or sulphur is incorporated in the pores of the catalyst; and (b) heating the sulphur-incorporated catalyst in the presence of a non-oxidizing atmosphere; presulphurized catalysts and their use in hydrocarbon conversion processes.</p> |
