In contrast to the prior art, in the molecular sieve prepared by this method, rare earth ions are located in sodalite cages, which is demonstrated by the fact that no rare earth ion is lost during the reverse exchange process. Moreover, the molecular sieve prepared by such a method has a molecular particle size D(v,0.5) of not more than 3.0 ?m and a D(v,0.9) of not more than 20 ?m.Type: GrantFiled: April 13, 2012Date of Patent: December 12, 2017Assignee: PetroChina Company LimitedInventors: Xionghou Gao, Haitao Zhang, Hongchang Duan, Chaowei Liu, Di Li, Xueli Li, Zhengguo Tan, Yunfeng Zheng, Xiaoliang Huang, Jinjun Cai, Chenxi Zhang
