Acetophenone/Dimethyl Adipate Hydrogenation Catalyst
Changzhou Ruihua's hydrogenation catalyst (KAH) has the characteristics of high conversion rate, good selectivity, high mechanical strength, and long life. It can be used as a general hydrogenation catalyst.
The hydrogenation of acetophenone can produce phenethyl alcohol, which is then dehydrated to produce styrene, while the hydrogenation of dimethyl adipate can produce hexanediol. When the KAH catalyst produced by Changzhou Ruihua is used in the hydrogenation of acetophenone to phenethyl alcohol and the hydrogenation of dimethyl adipate to hexanediol, it exhibits high activity and high selectivity.
The acetophenone hydrogenation reaction is carried out in an adiabatic fixed-bed reactor. Acetophenone and hydrogen are measured by a metering pump and a mass flow meter in a certain proportion and then enter the catalyst bed together. In the reactor, acetophenone undergoes a hydrogenation reaction under the action of the strip-shaped KAH catalyst, and the product phenethyl alcohol and the by-product ethylbenzene are produced with high selectivity. The conversion rate of acetophenone and the selectivity of phenylethanol are equal. Can reach more than 99%.
The hydrogenation of dimethyl adipate was carried out in the same pilot plant. Dimethyl adipate and hydrogen are respectively measured by a metering pump and a mass flow meter in a certain proportion and then enter the reactor together. Both the conversion rate of dimethyl adipate and the selectivity of hexanediol can reach more than 99%.
Ruihua’s KAH catalyst has undergone a 2000-hour life test, and the catalyst activity has not significantly decreased.
