Compact catalytic membrane reactor for chemical process intensification
Embodiments disclosed herein generally relate to an apparatus for simultaneous generation and separation processes. The apparatus provides a membrane module including a substrate, a catalytic layer and a membrane layer. The catalytic layer includes nano-sized particles. As a result, the apparatus can operate in sulfur-free and sulfur-laden feed gas environment for water gas shift (WGS) reactions while maintaining high reaction conversion.
