Abstract: | Design characteristics and performance of a novel reactor system, termed a hybrid adsorbent-membrane reactor (HAMR), have
been investigated for hydrogen production. The recently proposed HAMR concept couples reactions and membrane separation steps
with adsorption on the membrane feed-side or permeate-side. Performance of conventional reactors has been significantly improved
by this integrated system. In this paper, an HAMR system has been studied involving a hybrid-type packed-bed catalytic membrane
reactor undergoing methane steam reforming through a porous ceramic membrane with a CO2 adsorption system. This HAMR system is of potential interest to pure hydrogen production for fuel cells for various mobile
and stationary applications. Reactor behaviors have been investigated for a range of temperature and pressure conditions.
The HAMR system shows enhanced methane conversion, hydrogen yield, and product purity, and provides good promise for reducing
the hostile operating conditions of conventional reformers, and for meeting the product purity requirements. |
