| Popis: | This paper studies the methanol steam reforming intensification to enhance the hydrogen production in a multi-channel block type micro-reformer. The effects of operating parameters such as reforming temperature, space velocity and catalyst layer thickness on reforming performance are investigated. For optimized design and operating conditions, the 8 cm3 reformer unit produced 170 LH2/h containing on dry basis 75.0% H2, 23.5% CO2, 0.06% CH3OH and 1.44% CO at 648 K allowing the production of 218e255 W in a commercial PEMFC with 80% hydrogen utilization. This study shows that high methanol conversion can be achieved with high Pd/ZnO catalyst loading at 648 K with very low CO content ( The authors acknowledge financial support from the Spanish Ministry of Science and Innovation, Ministry of Economy and Competitiveness, FEDER funding (ENE2012- 37431-C03 Grant) and UPV/EHU (GIU11/13). |
