Feedstock Selective Hydrogenation Catalyst (Ys-qsh-01)

These Feedstock Selective Hydrogenation Catalyst (YS-QSH-01) is a kind of Palladium based noble metal catalyst, suitable for selective hydrogenation of dienes in C4 alkylation feedstock into monoolefin. It has excellent mechanical strength, activity, selectivity, stability, strong sulfur tolerance as well as long service life For the hydrogenation of highly-unsaturated C3 - C6 hydrocarbons from in other feedstock, the catalyst also has high selective hydrogenation ability. Its performances stand at international advanced level, and it's in the leading position in domestic industry.

1Excellent strength, stability and high sulfur tolerance due to the carrier with special crystalline structure.
2High activity, selectivity and stability due to the electronic structure of active component Pd modified by new promoter.
3Excellent performance due to the suitable thickness and uniform distribution of active component on the surface of catalyst by unique impregnation process.
4Long service life, more than 3 years under normal operating conditions.

Suitable for the process of selective hydrogenation of dienes in C4 alkylation feedstock into monoolefin.

1 Pressure: 1.0-2.5MPa.
2 Liquid volumetric space velocity: 5h-1.
3 Inlet temperature: 50-70. SOR 50, can be gradually increased to 70 at the EOR
4 H2/diene molar ratio: 2.0-3.0, can be increased during operation, but no more than 4.0.
