ABSTRACT:
Regeneration of an aromatics processing catalyst is effected in the absence of a gas cooler and a gas-liquid separator with a continuous loop flow of an oxidizing gas stream by removing a portion of said continuous closed loop flow and introducing therein a quantity of a low moisture content molecular oxygen containing gas effective to maintain a molecular oxygen content no greater than 1.0 mole percent and a water partial pressure no greater than about 1.0 psi.
