ABSTRACT:
A method for regenerating a hydrocarbon conversion catalyst wherein at least a portion of a halogen-containing compound is precombusted in a precombustion zone, and the catalyst is regenerated in the presence of the halogen. By precombusting the halogen-containing compound in a precombustion zone rather than in the regeneration zone, this invention decreases the risk of permanent catalyst deactivation and of costly equipment damage in the regeneration zone. This method is adaptable to many processes for the catalyst conversion of hydrocarbons in which deactivated catalyst particles are regenerated in a moving bed.
