Claim 24:
25. The process of claim 1, wherein:
the catalyst further comprises up to 10 wt % of a promoter disposed on the support based on the weight of the support,
the promoter comprises Sn,
the Group 8-10 element comprises Pt,
the support comprises a mixed Mg/Al metal oxide,
in step (I), the hydrocarbon-containing feed and catalyst are contacted in the presence of steam at an amount from 0.5 vol % to 20 vol %, based on a total volume of any C2-C16 alkalies, any C4-C16 cyclic alkanes, and any C8-C16 alkyl aromatics in the hydrocarbon-containing feed,
in step (II), the coked catalyst and oxidant are contacted at a temperature in a range from >750° C. to 1,100° C., and
in step (IIa), the regenerated catalyst and the reducing gas are contacted at a temperature ≥720° C. for a time period of <1 minute.
