摘　　要：本文采用固定床反应装置考察了稀土镧改性的非晶态镍基催化剂二氧化碳甲烷化催化反应活性。实验结果表明:氧化镧的添加,提高了非晶态镍的晶化温度,阻止了镍的聚集,提高了镍的分散度,从而提高了二氧化碳甲烷化的活性和稳定性。The catalytic performance of methanation of CO2 was investigated on the amorphous nickel-based catalysts modified by La2O3 in the fixed bed reactor.Research results showed that methanation of carbon dioxide activity was increased on the amorphous nickel-based catalysts modified by lanthanide oxide.XRD and TEM analysis shows that the nickel dispersion and crystallization temperature of amorphous nickel are greatly improved.
