NAY molecular sieve
NaY molecular sieve is a supercage crystal composed of AlO4 tetrahedra and SiO4 tetrahedra, featuring a unique three-dimensional pore structure with a pore opening size of 0.74 nm.
Y-type molecular sieve is the most widely used molecular sieve. After modification, it serves as the core active component of fluid catalytic cracking catalysts, facilitating petroleum refining. It is also utilized in hydrocracking, isomerization, and alkylation catalysts to enhance reaction efficiency and product quality.
NaY zeolite without exchange modification is an efficient desiccant. Furthermore, it can also be utilized for the removal of harmful gases and pollutants, as well as for enhancing the performance of lithium-ion batteries and supercapacitors.
