Abstract

Regeneration process by combustion of the deposits formed on a catalytic mass in the course of operations, such as cracking or reforming, in the course of which at least one gas such as hydrogen is produced capable of forming a detonating mixture with the oxidizing gas used, this procedure consisting of sweeping said catalytic mass with the aid of an inert gas stream, such as nitrogen, afterwards, when this mass is practically free of gas capable of forming a detonating mixture with the oxidizer, in introducing the oxidizer into the forwarded scavenging gas stream on the catalytic mass and being characterized in that the oxidizer is introduced into the scavenging gas in the form of an oxidizing mixture obtained by mixing the oxidizer with a portion of scavenging gas derived from sweep current.
