USY molecular sieve is widely used in the petrochemical industry for catalytic cracking processes. It enhances the conversion of heavy hydrocarbons into lighter, more valuable products like gasoline and diesel. Its high thermal stability and acidity make it effective in breaking down large molecules efficiently. Additionally, it is employed in refining processes to remove impurities and improve fuel quality. It also finds applications in adsorption and separation processes due to its uniform pore structure, which allows selective separation of molecules based on size. In environmental applications, it is used to capture volatile organic compounds (VOCs) and reduce air pollution. Its versatility and efficiency make it a critical component in industrial and environmental processes.
