Hydrogenation Catalyst for Unsaturated Hydrocarbon and aromatic Hydrocarbon
1. Application
The Catalyst can be used in the following processes:
A. Benzene hydrogenation to cyclohexane.
It can hydrogenate about 100% benzene to less than 100ppm.
B. Phenol hydrogenation to cyclohexanol.
C. Hydrotreating of industry coarse hexane and other solvent oil.
D. Hydrogenation of white oil.
E. Hydrogenation of lube.
F. Organic sulfides removal of liquid hydrocarbon.
The Catalyst is mainly used for hydrogenation of unsaturated aliphatic hydrocarbon, aromatic hydrocarbon and organic sulfides removal of liquid hydrocabon. After hydrogenation, the content of remained aromatic hydrocarbon or unsaturated hydrocarbon can be decreased to ppm grade, and the sulfides content of liquid hydrocarbon can be decreased to less than 0.1ppm.
The catalyst has been successfully used in many industry units. its comprehensive performance is superior to the same kind of products.
