USY molecular sieve is widely used in the petrochemical industry for catalytic cracking processes. It enhances the conversion of heavy petroleum fractions into more valuable products like gasoline and diesel by providing a highly active and stable catalyst. Its unique structure allows for efficient cracking of large hydrocarbon molecules, improving yield and selectivity. Additionally, it is utilized in the refining of crude oil to remove impurities and improve fuel quality. In environmental applications, it aids in the reduction of harmful emissions by acting as a catalyst in exhaust gas treatment systems. Its high thermal stability and acidity make it a preferred choice for various industrial catalytic processes.
