| titleOfInvention | Synthesis method of ZSM-23 molecular sieve under high-speed stirring |
| abstract | The invention relates to a method for synthesizing a ZSM-23 molecular sieve under high-speed stirring, which comprises the following steps: (1) adding an aluminum source into a template-containing aqueous solution, and stirring to form a solution A; (2) adding a silicon source into an aqueous solution containing an alkali source to form a solution B; (3) adding the solution A into the solution B; then adding an ion regulator and seed crystals in sequence; (4) hydrothermal crystallization at 60-80 deg.c for 1-12 hr to produce homogeneous gel and primary structure unit; (5) crystallizing at 180 ℃ for 24-80h under 160-; (6) and washing, drying and roasting the hydrothermal crystallization product to obtain the pure-phase high-crystallinity ZSM-23 molecular sieve. The method can solve the problems of low heterocrystal phase and low crystallinity in the existing industrial production process of the ZSM-23 molecular sieve. |
