A series of alumina supported Pd-ZnO catalysts were sythesized and studied for mthanol steam reforming. Pd loading and Pd/Zn ratio were optimized to improve catalyst activies. Among all the catalysts studied, the catalyst with a Pd loading of 8.9wt% and a Pd/Zn molar ratio of 0.38 exhibited highest methanol conversion lowest CO selectivity. The significantly improved Pd-ZnO/AI2O3 catalyst activity was one of the main factors that the efficiency of a micro-scaled fuel processor was improved from 9% to 15%.
