Abstract:
Processes for upgrading a hydrocarbon. The process can include contacting a hydrocarbon-containing feed with fluidized catalyst particles that can include a Group 8-10 element or a compound thereof disposed on a support to effect one or more of dehydrogenation, dehydroaromatization, and dehydrocyclization of at least a portion of the hydrocarbon-containing feed to produce coked catalyst particles and an effluent. The process can also include contacting at least a portion of the coked catalyst particles with an oxidant to effect combustion of at least a portion of the coke to produce regenerated catalyst particles. The process can also include contacting at least a portion of the regenerated catalyst particles with a reducing gas to produce regenerated and reduced catalyst particles. The process can also include contacting an additional quantity of the hydrocarbon-containing feed with fluidized regenerated and reduced catalyst particles to produce additional effluent and re-coked catalyst particles.
