Preparation and Catalytic Performance of Cr2O3-ZnO Catalyst for Methanol Steam Reforming

采用共沉淀法制备了一系列Cr2O3-ZnO催化剂用于甲醇水蒸气重整制氢.用X射线衍射和N2吸附考察了Cr含量及焙烧温度对Cr2O3-ZnO催化剂物相结构的影响,并用不锈钢微通道反应器考察了催化剂的性能.结果表明,ZnO是催化剂的主要活性组分,Cr的加入使催化剂的比表面积有所降低,但明显提高了催化剂的活性和稳定性,并且CO选择性随Cr含量的增加而升高.当焙烧温度在500℃左右,Cr2O3含量在5.3%～17.6%范围内时催化剂性能较好
