    摘要: A process for activation of a hydroconversion catalyst, whereby said catalyst contains at least one metal or element of group VIII, at least one acid element and optionally at least one metal or element of group VI according to which a light petroleum fraction, at least one thionic compound and at least one nitrogenous compound are injected in said catalyst. This process is carried out such that the QS sulfur amount that is injected before the temperature of the catalyst reaches 250° C. is at least equal to half the QSO sulfur amount that is necessary for complete sulfurization of the catalyst.

    摘要: The present invention relates to a catalyst comprising an extruded essentially alumina-based support, constituted by a plurality of juxtaposed agglomerates partially in the form of packs of flakes and partially in the form of needles, and comprising at least one catalytic metal or a compound of a catalytic metal from group VIB, and/or optionally at least one catalytic metal or compound of a catalytic metal from group VIII. The catalyst also comprises at least one dopant selected from the group formed by boron, phosphorous, silicon (or a silica different from that subsequently added to the support) and halogens. The invention also relates to its use in a fixed bed reactor, for hydrorefining and hydroconverting hydrocarbon feeds.
