摘要：The invention concerns a regeneration process and the correspondingapparatus for regeneration of a reforming catalyst, the reforming operation beingcarried out in at least two reactors in series, through which the catalyst and the chargesuccessively flow, the pressure in the first reactor through which the catalyst and thecharge pass being under a pressure of between 3 and 8 bars.

The regeneration process is characterized in that the exhausted catalyst successivelymeets a first radial moving bed combustion zone 101, a second radial moving bedcombustion zone 105, an axial oxychlorination moving bed zone 107 and an axial

calcination moving bed zone 116, and that in the combustion zones the catalyst is treatedunder a pressure substantially equal to that which obtains in said first reactor, theburning gases are discharged from the second burning zone and are passed to a washingloop after having been previously mixed with the gases withdrawn from theoxychlorination zone and the calcination zone, that in the oxychlorination zone thecatalyst is treated in co-flow relationship by a mixture of a gas from the calcination zone

and a gas based on a chlorinated compound, and that in the calcination zone the catalystis treated in counter-flow relationship by at least a part of the gases from the washingloop.
