Abstract
Processes for upgrading a hydrocarbon. The process can include (I) contacting a hydrocarbon-containing feed with a catalyst that can include a Group 8-10 element or a compound thereof disposed on a support to effect conversion of the hydrocarbon-containing feed to produce a coked catalyst and an effluent. The process can also include (II) contacting the coked catalyst with an oxidant to effect combustion the coke to produce a regenerated catalyst. The process can also include (IIa) contacting the regenerated catalyst with a reducing gas to produce a regenerated and reduced catalyst. The process can also include (III) contacting an additional quantity of the hydrocarbon-containing feed with the regenerated and reduced catalyst. A cycle time from the contacting the hydrocarbon-containing feed with the catalyst in step (I) to the contacting the additional hydrocarbon-containing feed with the regenerated and reduced catalyst in step (III) can be ≤1 hours.
