The NAY 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 The pore size of NAY molecular sieve. 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.
NaY zeolite molecular sieves are Y-type zeolites without ion exchange. They have high relative crystallinity and silicon-aluminum ratio, relative crystallinity ≥88%, and SiO2 / Al2O3 molar ratio ≥5.2.
