Microporous membrane reactors for hydrogen production

• Recent advances in developments of high performance microporous membranes for H2 separation are described.
• Reviews on reactor configurations for microporous membrane reactors is presented.
• Applications of microporous membrane reactors in H2 production (SRM, WGS, among others) are summarized.

Membrane reactors that combine catalytic reactions and separation through membranes in a single unit are attracting an increased amount of research interest for their application in the continuous production of pure hydrogen. These reactors achieve this by using mechanically and chemically stable membranes with high perm-selectivity toward hydrogen. For realizing membrane reactor technology industrially, currently, the microporous membrane is a more economical alternative to the dense metal membrane. This review highlights recent developments in microporous membranes used for hydrogen-selective separation and introduces advances in different types of microporous membrane reactors. In addition, several applications of microporous membrane reactors for hydrogen production are presented.
