摘要
本文提出了采用国内廉价的2#原料,代替活性氧化铝,用一次搓成法和固体合成法新工艺,研制了9011#,9104#新型汽车尾气净化稀土催化剂,提高了催化剂的低温活性,降低了成本,为稀土催化剂的应用开辟了一条新路。
This paper relates to the preparation of two new types of RE catalyst for purification of auto exhaust, adopting impregnating and solid synthetic method. The cheap 2# raw material produced in home was used as catalytic support instead of active alumina. 9011# and 9104# autocatalyst have higher activity at low temperatrue and lower cost.
