铜铈复合金属氧化物催化剂催化分解N2O
Catalytic Decomposition of N2O on Cu-Ce Mixed Oxide Catalyst
摘要
Abstract
Cu-Ce complex oxide catalysts were prepared by impregnation method using honeycomb ceramics as carrier. The factors affecting N2O decomposition were studied, such as "(Cu) : "(Ce), loading amount of active component, calcination temperature and O2 atmosphere. The experimental results show that: The addition of CeO2 can lead to the significant improvement of CuO catalytic activity; When n(Cu) : n(Ce)=l : 1, the N2O decomposition rate is the highest and it can reach 85.8% at 500 ℃ of reaction temperature; For the catalyst with n(Cu) : n(Ce)=l : 1, the best mass loading amount of the active component is 18%, the best calcinations temperature is 500 ℃; O2 in the reaction atmosphere can inhibit the N2O catalytic decomposition reaction.关键词
