HYJH-202 catalyst is a noble metal palladium-based selective hydrogenation catalyst for alkylation feedstock carbon four diolefin selective hydrogenation process to generate mono-olefins, having a good mechanical strength, activity, selectivity and stability , but also has a strong sulfur-tolerant performance, long service life. for other raw materials in C3-C9 highly unsaturated hydrocarbons also has good selective hydrogenation. The catalyst performance indicators have reached the international advanced level in China in technology leadership.
■ Preparation of the catalyst support with a special crystal structure, improve the strength and stability and strength sulfur tolerant catalyst performance.
■ Add new additives modulation of palladium, palladium improve the electronic structure, improved catalytic activity, selectivity and stability.
■ unique catalyst impregnation process, allows active component palladium catalyst surface suitable thickness and uniform distribution of the palladium layer, improving the performance of the catalyst.
■ catalyst for long life, under normal operating conditions life of up to 3 years.
Uses and conditions of use
