Method for solvent-free solid-phase synthesis of LTA type molecular sieve
The invention discloses a solvent-free solid-phase synthesis method of an LTA type molecular sieve, the solvent-free synthesis of the molecular sieve refers to that no solvent is used or the use of the solvent is greatly reduced in the synthesis process of the molecular sieve, and the molecular sieve synthesis system is mainly a solid phase. In the solvent-free synthesis process of the LTA type molecular sieve, a grinding material exerts a mechanical force effect on raw materials such as a silicon source, an aluminum source and an alkali source for synthesizing the molecular sieve. Different from a traditional rotary or stirring hydrothermal reaction kettle, the molecular sieve nucleation and crystallization growth process can be promoted by introducing mechanical force in the process. Meanwhile, the solvent-free solid-phase synthesis system can effectively reduce the use of a template agent and a solvent, reduces the generation of wastes and reduces the energy consumption of chemical synthesis, and is lower in equipment cost and easy to operate.
本申请公开了一种LTA型分子筛无溶剂固相合成的方法，所述分子筛固相无溶剂合成是指在合成分子筛的过程中不使用溶剂或者大大减少溶剂的使用，分子筛合成体系主要为固相。在无溶剂合成LTA型分子筛的过程中，研磨材料对合成分子筛的硅源、铝源和碱源等原料施加机械力的作用。区别于传统的旋转或带搅拌的水热反应釜，该过程机械力的引入可以促进分子筛成核与结晶生长过程。同时，无溶剂固相的合成体系可以有效的降低模板剂和溶剂的使用，减少废弃物的产生和降低化学合成的能量消耗，设备成本较低且易于操作。
