Abstract
The present invention describes a combustion zone for a regenerative catalytic unit for the continuous regeneration of catalyst, said combustion zone having an annular shape and being divided into at least two combustion stages, each stage being divided into a number N of radial sectors, which are substantially equal, the catalyst flowing under gravity from one sector of the first combustion stage to the sector located in vertical alignment with the second combustion stage by means of drop legs, and the movement of the combustion gas being such that the combustion gas passes in succession through all of the sectors of the first combustion stage in any order, then all of the sectors of the second stage in any order.
