Hydrotreating catalyst for high-temperature pyrolysis gasoline is a high-performance catalytic material designed for the selective removal of impurities such as sulfur, nitrogen, and unsaturated hydrocarbons from pyrolysis gasoline under elevated temperature conditions. Engineered with advanced metal-supported formulations, it ensures optimized hydrogenation efficiency, superior thermal stability, and extended operational lifespan. This catalyst is widely used in petrochemical refining, fuel purification, and hydrocarbon upgrading applications, delivering reliable performance in controlled high-temperature reaction environments.
Product Overview
This hydrotreating catalyst for high-temperature pyrolysis gasoline is based on alumina as the support and contains palladium and other precious metal active components, along with special additives. It is mainly used for selective hydrogenation in the gasoline high-temperature pyrolysis process (C6~C7, C6~C8, C5~C9 fractions). The catalyst features excellent water resistance, arsenic resistance, and sulfur tolerance, improving hydrogenation stability and showing significant performance improvement compared to the PGH-10A catalyst. It has been widely applied in industrial units, including Yanshan Petrochemical, Shanghai Petrochemical, and Lanzhou Petrochemical, with excellent results.
