摘要： The present invention concerns a process for ex situ oxidizing passivation of hydrocarbon hydroconversion catalysts, in particular for hydrotreatment in their sulphurized states, in which the sulphurized catalyst undergoes two treatments: contact with an oxidizing gas stream, and contact with an organic liquid (for example hydrocarbon) which partially fills its pores.

摘要： The invention concerns a process for fluidising a catalyst or an adsorbent in a furnace which is fixed but the fluidised bed advances, optionally with rotation, in the presence of another inert solid with a granulometry which is different from that of the catalyst or the adsorbent, in the presence of a fluidisation gas, to carry out either stripping of a catalyst or an adsorbent or regeneration of a catalyst or an adsorbent in the furnace.

摘要： The invention relates to a process for ex-situ presulfurization of porous particles of a hydrocarbon hydroconversion catalyst that contains at least one metal or metal oxide, comprising bringing catalytic particles into contact with a presulfurizing agent that contains elementary sulfur and at least one organic liquid. It is characterized in that the process comprises preparing the presulfurizing agent in the form of an essentially homogeneous liquid and impregnating the catalyst particles with said liquid, with said elementary sulfur consequently being incorporated for the most part into the pores of the catalyst.

摘要： A process for ex-situ treatment of a catalyst that contains at least one hydrogenating phase, and at least one amorphous silica-alumina or a zeolite that contains acid. The process includes: a stage for introducing nitrogen by contact at a temperature that is less than 100° C., with at least one basic nitrogen-containing compound that is ammonia or a compound that can be decomposed into ammonia, the compound being introduced at a rate of 0.5-10% by weight (expressed in terms of N), and a sulfurization/activation stage with a gas that contains hydrogen and hydrogen sulfide at a temperature of at least 250° C., with this stage being carried out before or after the stage for introducing said nitrogen-containing compound, and optionally drying the catalyst that is obtained. This treatment allows a rapid, effective start-up on the hydrocracking unit.
