摘要：

This work describes a novel method to synthesize. NaY zeolite at high temperature(100-140 T) by using NaY seeds solution as a silica source, which is also a method for the activation of silica source in the synthesis of NaY zeolite. Conventionally, the synthesis temperature of NaY zeolite from water glass is about 100 degrees C, and higher temperature( > 100 T) leads to the formation of impurity. However, this work shows that high-temperature synthesis(100-140 degrees C) still exhibits a pure phase NaY. It is very interesting that, compared with conventional temperature, high-temperature in the synthesis of NaY zeolite has obvious advantages such as short crystallization time and high n(Si)/n(Al) ratio in the product. More importantly, this method is possible to extend to the synthesis of NaA, NaX, Omega, ECR-1 and MOR.
