Abstract:
A process for performing an exothermic oxidation reaction using a moving bed containing a solid convertible material that can be oxidised from a lower oxidation state to a higher oxidation state, said moving bed being in the form of a rotatable member having a multiplicity of through flow passages, the walls of which are formed from, or are coated with, or which passages contain, said convertible material, said process comprising:a) continuously rotating said rotatable member about its axis, whereby each flow passage is moved through a succession of zones including an oxidative regeneration zone, a reaction zone, and then returned to the oxidative regeneration zone;b) a regeneration stage, comprising passing an oxidising fluid stream through said oxidative regeneration zone, whereby the convertible material that is in said oxidative regeneration zone is oxidised from said lower oxidation state to said higher oxidation state;c) a reaction stage, comprising passing feedstock through said reaction zone, whereby said feedstock is reacted to give a products stream with the concurrent reduction of the convertible material to its lower oxidation state.
