摘要

以钴、铜为活性金属，采用等体积浸渍法制备Co-Cu双金属催化剂，考察了不同载体的Co-Cu双金属催化剂对CH4-合成气梯阶转化直接合成C2+含氧化合物的影响，并进行了XRD、NH3-TPD和H2-TPR表征及相应的分析。实验结果表明，载体对催化剂催化性能有较大的影响，不同载体的催化剂对CH4-合成气两步梯阶转化反应的活性高低顺序为Co-Cu/TiO2＞Co-Cu/Al2O3＞Co-Cu/SiO2，Co-Cu/TiO2催化剂对C2+含氧化合物的选择性为79.9%。这归因于TiO2载体与活性金属Co、Cu之间适宜的相互作用及载体对Co-Cu良好的分散性能。此外，Co-Cu/TiO2催化剂还具有反应所需的表面酸量及适度的中强酸度。

Abstract

Co-Cu bimetallic catalysts were prepared by equal volume impregnation.The effect of supports on Co-Cu bimetallic catalyst performance was investigated for direct synthesis of the performance of C2+ oxygenates from CH4 and CO by a step-wise reaction technology.Those catalysts were characterized by XRD，NH3-TPD and H2-TPR.The results show that supports have a greater impact on catalytic performance，the activity order of catalysts loaded on different supports for step-wise conversion of CH4 and syngas is Co-Cu/TiO2＞Co-Cu/Al2O3＞Co-Cu/SiO2 and the highest selectivity of C2+oxygenates is 79.9%.It is concluded that there is the interaction between the TiO2 and the active metal Co-Cu and the good dispersion of Co-Cu/TiO2 in the catalyst with high activity.In addition，the amount of surface acidity and moderate acid strength also favor the reaction.
