Abstract

Methods for the operation of membrane reactors (MRs) are disclosed for the efficient production of hydrogen-enriched fuel blends with tunable composition and high hydrogen recovery at both elevated and isobaric pressure operation. These methods enable use of greatly reduced operating temperatures relative to packed bed reactors (PBRs) and elimination of the need for a secondary separation unit operation. These methods provide greater productivity and hydrogen recovery while relaxing membrane selectivity constraints relative to conventional MR operation.
