Processes and systems for the conversion of hydrocarbons

A process for endothermic dehydrogenation, the process comprising:

• disposing a catalyst material in a moving bed reactor having at least one reaction zone, the moving bed reactor comprising a heat exchanger containing a heating medium, wherein the catalyst material and the heating medium do not directly contact one another, and wherein at least 50% of delta enthalpy of the at least one reaction zone is provided by transfer of heat through the heat exchanger to the catalyst material;
• and
• contacting a feedstock comprising hydrocarbons with the catalyst material in the at least one reaction zone of the moving bed reactor under reaction conditions to convert at least a portion of the hydrocarbons to a first effluent comprising a product comprising alkenes, alkynes, cyclic hydrocarbons, and/or aromatics.
