Influence of the Preparation Conditions on the Reaction Performance on Steam Reforming of Methanol in a Cu/Zn/Al model catalyst



The model Cu/Zn/Al catalysts with different calcination temperature were prepared by hydrothermal method. The catalysts were characterized by XRD, BET, SEM, CO2-TPD, H2-TPR, TG, CH3OH-TPD and CO2+H2-TPSR. The effect of different calcination temperature on structure, stability and catalytic performance for methanol steam reforming at the conditions of 200-320℃ was also represented. The results of present study show that the different calcination temperature of Cu/Zn/Al catalysts had an obvious influence on the physical characteristics and catalytic performance of the methanol steam reforming.
