Abstract
A catalyst is regenerated by an inventive process using a heat exchange fluid such as superheated steam to remove heat during the process relying on efficient heat transfer (e.g., enabled by the microchannel reactor construction) in comparison with prior art heat exchange relying on a phase change, e.g. between water and (partial or complete vaporization) steam, allows simplification of the protocols to enable transition at higher temperatures between steps which translates in reduced duration of the regeneration process and avoids potential water hammering risks.
