摘要
研究铁轻稀土、铁锰轻稀土复合氧化物催化剂对苯的催化活性,发现铁锰轻稀土复合氧化物催化剂对苯具有较理想的完全氧化活性;同时还研究了稀土用量及添加微量贵金属钯对催化剂性能的影响,发现轻稀土有一个恰当的添加比例,另外还发现添加微量钯可提高催化剂的初活性。该催化剂用于柴油机尾气的净化取得了较为满意的结果。
In the research of complete oxidation of benzene by the catalysts of Fe-Ln and Fe-Mn-Ln compound oxides,it was found that complete oxidation of benzene by catalyst of FeatMn-Ln compound oxides was great. In the research of influence of the mass ratio mixed light rare earth oxides and adding a few Pd on catalytic activity,it was found that when the mass ratio mixed light rare earth was appropriate, the catalytic activity was better,adding a few Pd could improve the catalytic initical activity. The efficiency of actalytic purification on the tail gas of diesel using this catalyst was perfect.
