Abstract

PURPOSE: To enhance catalyst regenerating efficiency with maintaining the strength of the catalyst by intermittently charging catalyst little by little from an atmosphere of ordinary or reaction temp. into a hot atmosphere of a regenerator kept at regeneration temp. and rapidly heating it in a short time.
