Features: 

Catalyst YH-GDH*1 is a kind of Palladium base  noble metal catalyst, suitable for selective hydrogenation of highly unsaturated hydrocarbons in pyrolysis gasoline. It has excellent mechanical strength, activity, selectivity, stability, strong sulfur tolerance as well as long service life. Its performances have reached world advanced  level, and it’s in the leading position in domestic industry.
Excellent strength, stability and high sulfur tolerance due to the carrier with special crystalline structure .
High activity, selectivity and stability due to the electronic structure of  active component Pd modified by new  promoter.
Excellent performance due to the suitable thickness and  uniform distribution of active component on  the surface of catalyst by unique  impregnation process.
Long service life,   more than 3 years under normal operating conditions.

Applications and operating condition:

Suitable for the process of selective hydrogenation of highly unsaturated hydrocarbons in pyrolysis.
Pressure 1.**4.0MPa.
Liquid volumetric space velocity of  fresh feed  <5h*1.
Inlet temperature  ****5°C,SOR *5°C, can be increased gradually to *5 °C at EOR.
