中文摘要：

采用等体积浸渍法制备了含金属助剂钒（V）和钼（Mo）的Co-Pd/TiO2催化剂,在固定床反应器装置上考察了该催化剂催化CH4和CO2反应合成乙酸的性能,用XRD,TPD和TPR等技术表征了催化剂.结果表明,V和Mo的加入量能影响载体的结晶度,促进活性金属的还原,调节催化剂表面酸性,提高活性金属在载体表面的分散度,从而影响催化剂的催化活性.

英文摘要：

Co-Pd/TiO2 catalysts with V and Mo were prepared by incipient impregnation method.The catalysts were evaluated in fixed-bed reactor,and its catalytic activities for the conversion of CH4-CO2 to acetic acid were studied.The catalyst characterization were determined by XRD,NH3-TPD and H2-TPR.The results showed that the addition of V and Mo affected the carrier crystal and superficial acid state,and was propitious to active metal reduction and the distribution of acetive metal on the carrier surface,thereby promoted the catalytic activity.
