摘要
A method for synthesizing a nanoscale molecular sieve SAPO-34 and a catalyst based on a molecular sieve SAPO-34 and their application are proposed. The SAPO-34 nanomolecular sieve is synthesized by adding a microporous matrix agent containing functionalized organic silane for hydrothermal synthesis. The SAPO-34 nanoscale molecular sieve is calcined to produce a catalyst based on the SAPO-34 nanomolecular sieve. The specified catalyst can be used in the reaction of obtaining a low-carbon olefin from an oxygenated compound. The SAPO-34 nanomolecular sieve obtained by this method has a pure crystalline CHA phase. In addition, the catalyst based on the nanomolecular sieve SAPO-34 obtained by this method has good catalytic properties in the MTO reaction, the catalyst service life is significantly increased and the selectivity of the low-carbon olefin is improved.
