Publication number: 20230339767Abstract: An H-type molecular sieve having the CHA framework type is directly prepared through hydrothermal synthesis by using the compounds with the chemical formulas (C4H8NO)3PO and/or (C4H8NO)2PO(C4H10N) as structure-directing agents. The structure-directing agent has a molecular topological structure, which is conducive to quickly and efficiently building a molecular sieve having the CHA framework type, so that the prepared product has a regular morphology and high relative crystallinity. The synthesis method can directly synthesize the H-type molecular sieve having the CHA framework type with a relative crystallinity greater than 95%. The molecular sieve product can be obtained by direct drying and calcination without an ammonium exchange process, so the synthesis method is simple, easy to perform, and suitable for large-scale production.Type: ApplicationFiled: June 20, 2023Publication date: October 26, 2023Applicants: CHINA AUTOMOTIVE TECHNOLOGY AND RESEARCH CENTER CO., LTD, CATARC AUTOMOTIVE TEST CENTER (TIANJIN) CO., LTDInventors: Kaixiang LI, Zhenguo LI, Xiaoning REN, Congjie LV, Jianhai WANG, Lingfeng JIA, Yuankai SHAO, Cheng LV
