I、Product introduction
Zeolite y is hexagonal structure with an average pore diameter of 0.74nm. It has the same structure as the x-type molecular sieve, except that the y-type molecular sieve has a high si-al ratio and strong hydrothermal stability, so it is more widely used.The y-type molecular sieve is the most used among all the molecular sieves.Modified Y zeolite is the main component of FCC catalyst.Unexchanged NAY molecular sieve is also an efficient desiccant and catalyst.
Zeolite y includes NaY、ammonium Y(NH4Y)、Hydrogen Y(HY)、UltraStable Y(USY)、rare earth Y(RY) and so on.
II、Product application
1. Adsorption of VOCs in environmental protection industry
2. Used for production catalytic cracking catalyst FCC in bulk
3. Used for making catalytic cracking catalyst
4. Used for making hydrocracking catalyst
5. For the production of efficient adsorption separation purification agent and desiccant
6. Spray on the concentrated runner to absorb VOCs
