NaY molecular sieve is a high-performance synthetic zeolite designed for efficient gas separation, adsorption, and catalytic applications in industrial processes. Featuring a well-defined pore structure and superior ion-exchange capacity, it selectively removes impurities such as CO₂ and moisture from gas streams while enhancing catalytic activity. This molecular sieve is widely used in petrochemical refining, air separation, hydrogen purification, and large-scale hydrocarbon conversion, delivering reliable adsorption and catalytic efficiency for continuous industrial operations.
Overview
NaY molecular sieve features a unique eight-faced zeolite cage structure. Compared to A-type and X-type molecular sieves, NaY has a higher silicon-to-aluminum ratio and larger pore size, offering superior selectivity, adsorption activity, thermal stability, and acid resistance. NaY molecular sieve is widely used in petroleum refining, natural gas treatment, and as a catalyst support, providing enhanced stability and efficiency for various processes.
