ABSTRACT:
A catalyst regeneration process wherein a platinum-iridium catalyst promoted with one or more of copper, sulfurous acid or sulfuric acid, or selenium components, preferably a platinum-iridium-selenium catalyst, is contacted with naphtha and the naphtha reformed at fluidized bed or magnetically stabilized fluidized bed severities for a period of at least 0.25 hours or at cyclic severities for a period of at least about 60 hours, or at semi-regenerative severities for a period of at least about 600 hours, and the catalyst then regenerated by contact with hydrogen.
