ABSTRACT:
A method is disclosed for regenerating particulate catalyst used in a hydrocarbon conversion process such as catalytic reforming. The method is especially applicable to moving bed reactor systems. The catalyst being regenerated slowly moves downward as a dense bed which is contacted with different gas streams at different elevations within the regeneration zone. The invention involves employing a portion of relatively hot combustion gas as a heating gas stream, with the remainder of the combustion gas being cooled and recycled to the combustion zone. This eliminates the need to employ a heater to provide a suitable heating gas stream.
