1.high strength, excellent selectivity;
2.good sulfur-bearance
The hydrogenation catalyst, using alumina as a carrier, with platinum as the main active component, mainly used in benzene hydrogenation to cyclohexane. The catalysts has lots of advantages, such as high strength, good activity, excellent selectivity, good sulfur-bearance performance, and still working well in the condition of high space velocity. At present, the catalyst has been successfully used in several industrial devices.
