A series of Ni/La₂O₃-ZrO₂ catalysts were prepared by homogeneous precipitation, template or sol-gel technique and used for hydrogen production from coke oven gas by CO₂ reforming. The catalysts were characterized by BET, XRD, TPR, TPH, TEM and TG–DSC. A study is also carried out to observe the effect of lanthana loading on the reforming reaction. TPH results indicated the presence of more than two types of carbonaceous species on the used catalysts, which are categorized based on temperature difference. The low-temperature carbon species could be considered as the active sites for the reforming reaction. Experiments and TG-DSC results revealed that all of the catalysts present good catalytic performance and excellent anti-carbon property. The test results showed that the catalysts prepared by sol-gel method exhibited the highest catalytic activity due to their suitable pore size distribution. The Ni/La₂O₃-ZrO₂ catalyst with 8 wt% lanthanum oxide loading provides the best catalytic activity, which will be promising application on catalytic CO₂ reforming of COG in the future.

采用均相沉淀法，模板法或溶胶-凝胶法制备了一系列Ni / La ₂ O ₃ -ZrO ₂催化剂，并利用CO _2将其用于焦炉煤气制氢。重整。催化剂的特征在于BET，XRD，TPR，TPH，TEM和TG-DSC。还进行了一项研究，以观察藤黄负载对重整反应的影响。TPH结果表明，所使用的催化剂上存在两种以上的碳质物质，这些碳质物质是根据温度差进行分类的。低温碳物质可以被认为是重整反应的活性位点。实验和TG-DSC结果表明，所有催化剂均具有良好的催化性能和优异的抗碳性能。测试结果表明，通过溶胶-凝胶法制备的催化剂由于具有合适的孔径分布而具有最高的催化活性。Ni / La ₂ O ₃ -ZrO ₂负载氧化镧含量为8 wt％的催化剂提供了最佳的催化活性，这将在未来COG的催化CO ₂重整中具有广阔的应用前景。
