Introduction to hydrogenation reactors

First, one of the Reactor types is introduced: Hydrogenation Reactor

Generally speaking, the Hydrogenation Reaction Kettle can be divided into two categories: one is the traditional mixing type reaction kettle, container gas within the liquid phase is not cycle, the upper space is not intermiscibility of gas and liquid, and the density difference is larger, not in reaction kettle, the reaction gas accumulation in the upper part of the reactor space, the serious influence the reaction rate, at the same time, the suspension of solid catalyst uneven also restricted the reaction rate; The other is the reaction kettle in which the gas is circulated in the liquid phase. Gas-liquid reaction is a reaction that is often encountered in petrochemical, fine chemical, biological chemical and pharmaceutical chemical industries. The typical application is catalytic hydrogenation, catalytic oxidation and fermentation. The size of the gas-liquid contact area significantly affects the reaction rate.

The equipment consists of a special set of components designed to meet the mass transfer requirements and shear effects, high gas internal circulation and turbulence. Motor driven by internal hollow blender rotates, near the fluid in the impeller is circular motion under the action of centrifugal force makes the blender imbibition is generated, and thus form a negative pressure zone, and its internal are connected to the gas through a hollow shaft, so that the gas flowing on the surface of the liquid suction blender to be dispersed in the liquid phase, Especially suitable for gas-liquid, gas-liquid-solid heterogeneous reaction processes, such as liquid phase catalytic hydrogenation, oxidation, amination, alkylation, fluorination, etc.
