在放电条件下对Cu/ZnO/Al 2 O3催化剂进行了甲醇水蒸气重整反应研究。在填充有催化剂的电极之间发生放电。放电的特征在于产生放电的放电电压和电功率。放电的存在对甲醇转化催化反应有协同作用。放电提供了改进的反应路径，导致催化剂活化或起燃的温度较低。放电部分控制重整过程中物种的产率和选择性。从反应动力学的角度检查了控制方面。探讨了放电与催化反应协同作用的机理。一个离散的反应路径，特别是吸附放电触发，被认为是最有可能的协同效应的机制。这些结果有望为理解等离子体-催化剂混合反应提供指导。(C)2013爱思唯尔有限公司版权所有。
Methanol-steam reforming was performed on Cu/ZnO/Al2O3 catalysts under an electric discharge. The discharge occurred between the electrodes where the catalysts were packed. The electric discharge was characterized by the discharge voltage and electric power to generate the discharge. The existence of a discharge had a synergetic effect on the catalytic reaction for methanol conversion. The electric discharge provided modified reaction paths resulting in a lower temperature for catalyst activation or light off. The discharge partially controlled the yield and selectivity of species in a reforming process. The aspect of control was examined in view of the reaction kinetics. The possible mechanisms for the synergetic effect between the catalytic reaction and electric discharge on methanol-steam reforming were addressed. A discrete reaction path, particularly adsorption triggered by an electric discharge, was suggested to be the most likely mechanism for the synergetic effect. These results are expected to provide a guide for understanding the plasma-catalyst hybrid reaction. (C) 2013 Elsevier Ltd. All rights reserved.
