Hydrogenation reactorThe efficiency of a hydrogenation reactor mainly depends on the form of the stirring blade of the hydrogenation reactor. Currently, in China, the stirring blade of a hydrogenation reactor is usually a downward pushing stirring blade. The advantage of this stirring blade is that it can fully mix hydrogen with the reaction material and catalyst to achieve a good reaction effect. Currently, our company has launched a relatively advanced stirring blade, which can not only fully mix hydrogen with the reaction material and catalyst, but also automatically suck the upper hydrogen below the liquid level to react with the material and catalyst again. This greatly shortens the reaction time and improves the product yield.
