从固液集成反应角度，建立了分子筛晶体生长动力学模型及三个推论。理论研究表明，晶化过程中的诱导期和晶化后期可以分别采用更简单的数学模型表示，对于全过程可以采用与在液相扩散速率限制区建立的修正的Ｌｅｃｈｅｒｔ模型形式上相同的模型描述。由水玻璃原料对Ｙ型分子筛晶化过程影响的理论模拟结果表明，较高模数水玻璃原料使得凝胶溶解速率增大可能是产品结晶度较高的原因之一。 From the perspective of solid-liquid integration reaction, the molecular dynamics model and three corollaries of molecular sieve crystal growth were established. Theoretical studies show that the induction period and the post-crystallization period in the crystallization process can be represented by simpler mathematical models, respectively, and the same model description can be adopted for the whole process in the same manner as the modified Lechert model established in the liquid diffusion rate-limited zone . The theoretical simulation of the effect of water glass on the crystallization process of Y zeolite shows that the higher rate of gel dissolution caused by the higher modulus water glass raw material may be one of the reasons for the higher crystallinity of the product.
