    摘要: The invention concerns a method for sulphurizing catalysts for hydrotreating of hydrocarbon feedstocks. The invention is characterised in that it consists in sulphurizing the catalyst in two steps: the first step consisting in sulphurization with tertiary mercaptan in the absence of hydrogen, and the second step, carried out consecutively in the same reactor, consisting of sulphurization with another sulphurizing agent in the presence of hydrogen. The catalysts thus sulphurized prove to be more active than those sulphurized by only the second step.

    摘要: This invention relates to the preparation and use of catalysts useful for hydroprocessing processes, such as hydrotreating, wherein said catalysts are formed by heating, at elevated temperature, in the presence of sulfur and under oxygen-free conditions, a composite of support material and one or more catalyst precursor salts containing a thiometallate anion of Mo, W or mixture thereof and a cation comprising one or more divalent promoter metals at least one of which is iron, wherein said promoter metal or metals are chelated by at least one neutral, nitrogen-containing polydentate ligand, and wherein said additional divalent promoter metal, if any, is selected from the group consisting of Ni, Co, Mn, Zn, Cu and mixture thereof.

    摘要: Hydrocarbon feeds are upgraded by contacting a feed, at an elevated temperature and in the presence of hydrogen, with a supported, self-promoted catalyst formed by compositing a porous, refractory inorganic oxide, support with one or more complex salts selected from the group consisting of (NR.sub.4).sub.2 [M(WS.sub.4).sub.2 ], (NR.sub.4).sub.x [M(MoS.sub.4).sub.2 ] and mixtures thereof wherein R is one or more alkyl groups, aryl groups or mixture thereof, wherein promoter metal M is covalently bound in the anion and is Ni, Co or Fe and wherein x is 2 if M is Ni and x is 3 if M is Co or Fe and heating said composite in a non-oxidizing atmosphere in the presence of sulfur and hydrogen and a hydrocarbon to form said supported catalyst.
