制备满足欧Ⅲ排放标准的摩托车尾气净化催化剂,制备需求的高性能稀土储氧材料和耐高温高比表面材料,在此基础上制备出密耦催化剂和三效催化剂。催化性能测定表明,密耦催化剂具有优异的低温活性和抗高温老化性能,三效催化剂具有优异的三效性能和抗高温老化性能,能满足欧Ⅲ排放标准的需求。
Preparation of motorcycle exhaust purification catalyst to meet Euro Ⅲ emission standards, preparation of high-performance rare earth oxygen storage materials and high temperature surface area materials, prepared on the basis of the close-coupled catalyst and three-way catalyst. Catalytic performance measurement shows that the close coupling catalyst has excellent low temperature activity and high temperature aging resistance. The three-way catalyst has excellent three-effect performance and high temperature aging resistance, and can meet the requirements of Euro Ⅲ emission standard.
