Y-Type Zeolite Molecular Sieve
FAU-Structured Zeolites for Petroleum Refining, Catalytic Cracking & Advanced Adsorption
Shanghai Zixuan Technology Co., Ltd. specializes in the development and supply of Y-type zeolite molecular sieves for petroleum refining, petrochemical processing and industrial adsorption applications.
Y-type zeolite is a crystalline aluminosilicate with a three-dimensional FAU framework, large pore openings of approximately 0.74 nm and interconnected supercages. Its unique pore structure, high surface area and adjustable acidity make it an important functional material for catalytic and adsorption processes.
Through controlled synthesis, ion exchange and material modification, different Y-type zeolite grades can be developed to meet the requirements of various catalyst formulations and industrial applications.
1. Product Features

Large Pore System: Approximately 0.74 nm pore openings and spacious internal cavities support molecular diffusion and catalytic reactions.
Adjustable Acidity: Acidity and catalytic properties can be tailored through ion exchange and post-treatment.
Flexible SiO₂/Al₂O₃ Ratio: Different compositions can be developed to meet specific thermal stability and catalytic requirements.
Modification Capability: Supports rare-earth exchange, ammonium exchange and other customized modification processes.
Versatile Applications: Suitable for catalyst manufacturing, petroleum refining and selected adsorption processes.
2. Main Product Grades
NaY Zeolite
The sodium form of Y-type zeolite, commonly used as a starting material for ion exchange and further modification. It is an important precursor for manufacturing HY, USY and rare-earth-modified Y zeolites.
NH₄Y Zeolite
The ammonium-exchanged form of Y zeolite, commonly used as an intermediate in the preparation of hydrogen-form and modified Y-type molecular sieves.
HY Zeolite
The hydrogen form of Y zeolite, featuring Brønsted acid sites that contribute to catalytic cracking and other acid-catalyzed reactions.
USY Zeolite (Ultra-Stable Y)
A modified Y-type zeolite developed to improve hydrothermal stability and maintain catalytic performance under demanding refining conditions. Widely used in FCC catalyst formulations.
REY / REUSY Zeolite
Rare-earth-exchanged Y-type zeolites designed to modify acidity, catalytic activity and structural stability. Commonly used in fluid catalytic cracking catalysts.
3. Main Industrial Applications
Fluid Catalytic Cracking (FCC)
Y-type zeolite is a key active component in FCC catalysts. Its large pore structure and acid sites facilitate the conversion of heavy petroleum fractions into lighter products, including gasoline-range hydrocarbons and LPG components.
Residue Fluid Catalytic Cracking (RFCC)
Modified Y-type zeolites, particularly USY and REUSY grades, are used in catalyst formulations for processing heavier feedstocks under demanding operating conditions.
Hydrocracking
Y-type zeolites can serve as the acidic cracking component in bifunctional hydrocracking catalysts, working together with hydrogenation metals to convert heavy hydrocarbons into lighter, more valuable products.
Petrochemical Catalysis
Depending on formulation and process conditions, Y-type zeolites can be used in hydrocarbon conversion, isomerization and other acid-catalyzed processes.
Adsorption & Separation
Their microporous structure also provides opportunities for selected molecular adsorption and separation applications, subject to the target molecule and process requirements.
