摘要： The invention concerns a process for regenerating a hydrocarbon hydroconversion catalyst containing a carrier, at least one group VIII noble metal and a halogen or halogenated compound.It is characterized by an operation in two regeneration zones (1) and (2). The gas effluent from the first regeneration zone (1) is used to feed the second regeneration zone. During the step of burning coke deposited onto the catalyst in the first zone, the heat amount generated during the combustion is used for preheating the feed of said first zone. The temperature of the effluent of said first zone is reduced, through said exchanger, to a value adapted to perform the burning step in the second zone. Additional air is supplied before introducing the gas into said second zone (2) in order to obtain a suitable oxygen concentration.

摘要： The hydrotreatment of hydrocarbons in the liquid phase is effected in a column containing a catalyst bed supported by a grid, wherethrough passes an ascending stream of the charge admixed with hydrogen which expands the catalyst bed, the perforations of the grid being small enough to prevent passage of the catalyst particles but large enough to permit passage of the hydrogen-charge mixture, the reaction effluent being withdrawn from the top of the column. The reactor column is provided with means between the hydrogen-charge mixture introducing means and the catalyst bed supporting grid for mixing and dispersing the combined liquid-gas charge.

摘要： The hydrotreatment of hydrocarbons in the liquid phase is effected in a column containing a catalyst fixed or moving bed supported by a grid, wherethrough passes an ascending stream of the charge admixed with hydrogen. The perforations of the grid are small enough to prevent passage of the catalyst particles but large enough for giving passage to the hydrogen-charge mixture. The reaction effluent is withdrawn from the top of the column.
