The hydrogenation reactor is a stirring reaction device for the chemical reaction of gas-liquid, liquid-liquid, liquid-solid or gas-liquid-solid three-phase chemical substances. The hydrogenation reactor can fully stir various chemical substances under high pressure, high temperature, high vacuum and other conditions. Strengthen the mass transfer and heat transfer process. The material of the hydrogenation reactor can be carbon-manganese steel, various grades of stainless steel, titanium and titanium alloys, nickel, Hastelloy, zirconium and their composite materials.

When the motor of the hydrogenation reactor drives the hollow agitator to rotate, the fluid near the agitator moves in a circular motion under the action of the impeller, and the centrifugal force generated generates self-absorption inside the agitator, causing the self-priming agitator to form a negative In the pressure zone, the interior of the self-priming agitator is connected to the gas phase through a hollow shaft, so that the gas on the liquid surface is continuously sucked into the agitator and redispersed in the liquid phase.

The main materials of the hydrogenation reaction kettle, the size and number of openings on the kettle body and the kettle cover, the heating method, the structure of the kettle, the stirring speed and the form of the stirring blade can be designed according to user requirements. There are multiple heating methods such as jacketed steam, jacketed thermal oil electric heating, jacketed oil bath circulation, far infrared, etc. for users to choose when ordering.

The inner surface of the hydrogenation reactor can reach the mirror polishing level for the inner surface of the kettle with polishing requirements, and the high-viscosity material can be processed into a conical bottom, which is convenient for discharging and cleaning. According to the manufacturing structure of hydrogenation reactors, it can be divided into three categories: open-type flat-lid reactors, open-type elliptical-headed reactors and closed-type reactors. Each structure has its scope of application and advantages and disadvantages.

The hydrogenation reactor has a volume of 0.1-10000 liters, an operating pressure of 0-35 MPa, and a magnetic coupling static seal. Hydrogenation uses a specially designed self-absorption stirrer and related supporting processes to make the reaction more complete. It is suitable for chemical reactions in high temperature, high pressure, high vacuum, flammable, explosive, toxic, and precious media.
