USY zeolite

Product Name USY zeolite Product Overview USY molecular sieve is a high-performance ultra-stable Y-type zeolite molecular sieve. It is prepared from artificially synthesized NaY zeolite molecular sieve through ammonium ion exchange modification and special ultra-stabilization treatment process. The product has excellent framework stability, regular pore structure and controllable silica-alumina ratio, with greatly improved thermal stability and hydrothermal stability, which effectively solves the problems of easy framework collapse and rapid activity attenuation of traditional NaY molecular sieve at high temperature. As the core active component of fluid catalytic cracking catalysts, it can also be processed into high-silicon HY molecular sieve after deep modification. It is a key functional powder material in the fields of petrochemical industry, fine chemical industry and environmental adsorption with excellent comprehensive performance.
