<p>An endothermic reaction is effected using a heat transfer bed, containing a variable oxidation state material, which is cycled through a succession of stages including an oxidative regeneration stage employing passage of a hot oxidising gas through the bed, a reductive regeneration stage employing passage of a reducing gas that is oxidised with the evolution of heat through the bed, each cycle of the process having a duration of less than 5 minutes. The convertible material comprised a chromic containing catalyst.</p> |
