A Hybrid Adsorbent-membrane Reactor (hamr) System for Hydrogen Production

Introduction An experimental study on the performance of a novel reactor system, termed the hybrid adsorbent-membrane reactor (HAMR) is described here. In the HAMR the reaction and membrane separation steps are coupled with adsorption. It was shown previously by our group that for esterification reactions this results in significantly improved performance. The focus in this presentation is on the use of the HAMR for hydrogen production. Experimental investigations are described of the HAMR for the water gas shift (WGS) reaction using hydrotalcite-type CO2 adsorbents and nanoporous H2-selective carbon molecular sieve membranes (CMS). The reactor characteristics have been investigated for a range of temperature and pressure conditions relevant to the WGS application, and are compared with the predictions of the mathematical model previously developed.
