摘要： A method for synthesizing a nano SAPO-34 molecular sieve, and an SAPO-34 molecular sieve catalyst and application thereof. A nano SAPO-34 molecular sieve is synthesized by adding a microporous templating agent and a templating agent having a functionalized organic silane to hydrothermal synthesis. The nano SAPO-34 molecular sieve is calcined to obtain a nano SAPO-34 molecular sieve catalyst. The catalyst can be used in a reaction for preparing low-carbon olefin from an oxygen-containing compound. The nano SAPO-34 molecular sieve obtained by this method has a pure CHA crystal phase. Moreover, the nano SAPO-34 molecular sieve catalyst obtained by this method has good catalytic performance in a MTO reaction, the service life of the catalyst is significantly prolonged, and the selectivity of the low-carbon olefin is improved.

摘要： A preparation method for a metal-modified SAPO molecular sieve is disclosed, characterized in adding a raw powder of the SAPO molecular sieve to a solution containing metal ions for performing ion exchange, and then washing and drying the obtained solid after ion exchange, so as to obtain the metal-modified SAPO molecular sieve. The metal-modified SAPO molecular sieve prepared has a relatively high degree of crystallinity, and the metal elements occupy the ionic positions in the channels and/or cages of the SAPO molecular sieve, and the metal-modified SAPO molecular sieve shows excellent catalytic performance in the catalytic reaction.
