AI Technical Summary
Existing silicon-rich LTA molecular sieve membranes suffer from problems such as excessively long synthesis time, low utilization rate of reaction equipment, and high energy consumption, which limit their industrial application in organic solvent dehydration processes.
By employing multiple strategies, including adjusting the alkalinity of the reactive sol, adding seed crystals for induction, and controlling the synthesis temperature, the crystallization process of silicon-rich LTA molecular sieve membranes was optimized, shortening the synthesis time and improving the membrane's high-temperature stability and pervaporation performance.
The synthesis time of silicon-rich LTA molecular sieve membranes was significantly shortened to 1/4, reducing energy consumption and improving the utilization rate of reaction equipment. A membrane with excellent pervaporation performance was obtained, which is suitable for the separation of organic solvents under high temperature and high hydrothermal conditions.
