Y molecular sieve is a high-performance synthetic zeolite designed for selective adsorption and catalytic applications in industrial processes. Featuring a well-defined microporous structure with superior ion-exchange capacity and enhanced thermal stability, it provides efficient hydrocarbon conversion, gas purification, and refining optimization. This molecular sieve is widely used in fluid catalytic cracking (FCC), petrochemical refining, and large-scale hydrocarbon processing, delivering reliable performance for continuous industrial operations.
Overview
Y molecular sieve is a microporous crystalline material with a framework structure. It consists of silicon-oxygen and aluminum-oxygen tetrahedra as the basic structural units. These units form different cyclic structures through Si-O or Al-O bonds, which are then linked together to create a β-cage structure with an eight-faced zeolite framework. Y molecular sieve is primarily used in catalysis, adsorption, and separation processes, and has important applications in petroleum refining and gas separation. Its pore size is approximately 0.74 nm, making it suitable for the separation and adsorption of various molecules.
