In this study, the methanol steam reforming reaction was carried out in a carbon membrane reactor (CMR)for hydrogen production. The behavior in the CMR was compared to that in a fixed-bed reactor (FBR) at thesame experimental conditions. The parameters temperature, carrier gas flow rate, and feed ratio wereinvestigated to better understand the separation effect of hydrogen in the CMR on the methanol conversionand product selectivity. The results showed that the CMR gives a higher methanol conversion than the FBRat all investigated operating conditions; the overall yields of hydrogen in the CMR and FBR are identical, buta CO-free hydrogen stream can be produced with the CMR, which could be directly used in a proton-exchange-membrane fuel cell.
