  • SAPO-34 molecular sieve having both micropores and mesopores and synthesis methods thereof
    Patent number: 9579637
    Abstract: The present invention relates to a SAPO-34 molecular sieve having both micropores and mesopores and synthesis method thereof. The mesopore diameter in the molecular sieve is in a range of 2-10 nm and the mesopore volume thereof is 0.03-0.3 cm3/g. Triethylamine is used as a template agent and the pore size modifiers are added to the synthesis gel at the same time in the synthesis process, thereby the prepared molecular sieve crystals have mesopore distribution besides micropores. The SAPO-34 molecular sieve synthesized in the present invention can be used as catalysts for conversion of oxygen-containing compounds to lower olefins.
