1. Product introduction

The HY molecular sieve is an octahedral zeolite type crystal structure. The large cage formed by β cages and hexagonal column cages is octahedral zeolite cages. The communicating window holes are twelve-membered rings and the average effective pore diameter is 0.74nm. This is HY molecular sieve pore size. The structure of X-type molecular sieve and Y-type molecular sieve are exactly the same, except that the Y-type molecular sieve has a high silicon-aluminum ratio and strong hydrothermal stability, so it is more widely used.

HY zeolite molecular sieve is a Y-type zeolite that undergoes hydrogen ion exchange. Its silicon-to-aluminum ratio has a large adjustable range. The maximum silicon-to-aluminum ratio can be 140 and maintains good crystallinity.
