    摘要: The invention relates to a process for sulfurization of catalysts for hydrotreatment, in particular the catalysts for hydrotreating refractory oxides by sulfurization, in which said catalysts are subjected to a sulfurization stage under a gas atmosphere that contains hydrogen sulfide (H2S), hydrogen (H2), and optionally a cover gas for dilution and in which the H2S/H2 molar ratio is more than 4 and the H2S partial pressure is at least equal to 1 kPa.Said sulfurization stage can be carried out in the hydrotreatment unit (sulfurization in situ) or, prior to the charging of the catalyst, in the hydrotreatment unit (sulfurization ex situ) and is generally carried out at a temperature of less than 600° C., preferably less than 500° C.The invention also relates to the catalysts that are sulfurized by said sulfurization process and their use for hydrorefining and/or hydroconversion/hydrocracking of hydrocarbon feedstocks.

    摘要: The invention concerns a process for converting heavy feeds carried out in a slurry reactor in the presence of hydrogen and in the presence of a catalyst comprising at least one catalytic metal or a compound of a catalytic metal from group VIB and/or VIII supported on alumina, the pore structure of which is composed of a plurality of juxtaposed agglomerates each formed by a plurality of acicular platelets, the platelets of each agglomerate being generally radially oriented with respect to the others and with respect to the centre of the agglomerate, said catalyst having an irregular and non-spherical shape and being mainly in the form of fragments, obtained using a process including the following steps: a) granulation starting from an active alumina powder having a low crystallinity and/or amorphous structure, to obtain agglomerates in the form of beads; b) maturing in a moist atmosphere between 60° C. and 100° C. then drying said beads; c) sieving to recover a fraction of said beads; d) crushing said fraction; e) calcining at least a portion of said crushed fraction at a temperature in the range 250° C. to 900° C.; f) impregnating with acid and hydrothermal treatment at a temperature in the range 80° C. to 250° C.; g) drying then calcining at a temperature in the range 500° C. to 1100° C. h) depositing at least one catalytic metal or compound of a catalytic metal from group VIB and/or group VIII by impregnation. The process of the invention employs a catalyst with a specific pore texture, shape and granulometry, resulting in improved performances.

    摘要: A process for hydrotreatment of a hydrocarbon feed comprises at least two reaction steps with intermediate fractionation of the effluent from the first step to eliminate unwanted impurities for the catalyst of the second step and to produce a desulphurized light liquid fraction. The intermediate fractionation comprises stripping the liquid effluent from the first step using low pressure hydrogen with rectification of the stripping vapours using a substantially desulphurized liquid reflux. The conditions for said fractionation and for the first hydrotreatment step can produce a substantially desulphurized light liquid fraction which is not supplied to the second step.
