Hydrogenation reaction refers to a reaction process in which hydrogen interacts with other compounds, usually in the presence of a catalyst. The hydrogenation reaction belongs to the category of reduction.

There are two types of commonly used hydrogenation reactors and reactors: one type is used for liquid phase hydrogenation process of high boiling point liquid or solid (solids need to be dissolved in solvent or heated and melted) raw materials, such as fat hydrogenation, heavy oil Hydrocracking, etc. Liquid phase hydrogenation is usually carried out under pressure, and the process can be batchwise or continuous. Intermittent liquid phase hydrogenation often uses an autoclave or bubbling reactor with a stirring device. The continuous liquid-phase hydrogenation can adopt a trickle bed reactor or a tubular reactor with three-phase continuous flow of gas, liquid and solid. Another type of reactor is used for continuous gas-phase hydrogenation processes, such as atmospheric gas-phase hydrogenation of benzene to cyclohexane, high-pressure gas-phase hydrogenation of carbon monoxide to synthesize methanol, etc. The reactor type can be tubular or tower. In the food field, it is mainly used to produce sorbitol, xylitol, maltitol and other continuous hydrogenation reactions, as well as intermittent hydrogenation reactions.

The stirring form of batch hydrogenation reactor is generally three-layer combined stirring, including paddle stirring, self-priming stirring and disc turbine dispersion stirring, which can also be selected according to user requirements. Our self-priming stirring paddle adds a set of riders, which can make the gas enter the hollow shaft of the stirring paddle more smoothly, and fully mix with the liquid gas.

Zhengwei hydrogenation reactor is equipped with CT4 explosion-proof motor and explosion-proof control box. All electrical components are explosion-proof configuration, so that customers can use it safely.
