摘要
以Ni-Cr-Fe合金金属作为催化剂的载体,以复合型金属氧化物MnCr2O4作为催化剂主要活性成分,通过XRD和SEM等分析手段对催化剂进行表征。选择环状六碳芳香烃C6H6为还原剂,选择催化还原NOx的实验评价催化剂的催化活性。结果表明:催化剂活性组分负载均匀,催化剂具有良好的催化活性,NOx的最高转化率为78%,C6H6最高转化率为81%,CO的生成量很少,几乎全部生成CO2。制备的催化剂具有良好的氧化还原性能。
With Ni-Cr-Fe alloy as catalyst supports and the MnCr2O4 complex oxide as main active component, The catalyst was characterized by XRD and SEM. Used C6H6 as reducing agent, the catalytic performance was investigated by selective catalytic reduction of NOx experiment. The results demonstrate that the catalyst is homogeneous, exhibits high catalytic activity, the conversion ratio of NOx is up to 78%, the conversion ratio of C6H6 is up to 81%, the formation amount of CO is less, nearly completely produce CO2. The catalyst has good redox property.
