ABSTRACT:
A method is described for the regeneration of a hydrocarbon conversion catalyst that has become deactivated by carbonaceous material deposition where the catalyst comprises a nonacid zeolite and a Group VIII metal component. The method comprises the steps of (1) removing a substantial portion of the carbonaceous material from the catalyst by combustion with an oxygen-containing gas in the presence of a halogen, and (2) reducing the catalyst in the presence of hydrogen.
