ReY (rare earth Y) molecular sieve is obtained by modifying NaY with Re ions. It belongs to the faujasite type. The faujasite cage is its main cavity. It is the same as the other four through the twelve-membered oxygen ring. The faujasite cages are connected. The 12-membered ring pore diameter is 0.74nm. It is the main channel of the Y-type molecular sieve. The structure of the X-type molecular sieve and the Y-type molecular sieve are exactly the same. Therefore, the use is more extensive.
2. Product application
The
Y-type molecular sieve is widely used due to its structure and performance
characteristics, and the modified Y-type molecular sieve is the main active
component of the fluidized catalytic cracking catalyst. It is used in catalytic
cracking, isomerization and deolefin reaction, and can also be used in VOC
adsorbent, etc.
