Features 
HYJH-201 catalyst is a precious metal palladium selective hydrogenation catalyst for pyrolysis gasoline highly selective hydrogenation of unsaturated hydrocarbon processes. The catalyst has high mechanical strength, activity and selectivity, high stability, but also has strong resistance to sulfur-performance, long service life. The catalyst performance indicators have reached the international advanced level in the domestic leading position in technology. 
■ carrier has 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
applicable to pyrolysis gasoline highly selective hydrogenation of unsaturated hydrocarbons process. 
■ Operating pressure: 1.5-4.0MPa 
■ fresh oil liquid hourly space velocity: <5h-1 
■ inlet temperature: 40-70 ℃, initial use of 40 ℃, using the end can be gradually increased to 70 ℃.
