The difference between a hydrogenation reactor and an autoclave is whether it is explosion-proof or not, for which the hydrogenation reactor requires some special facilities. This article provides a brief explanation of this point.
The difference between the hydrogenation reactor （hydrogenated reaction reactor）and the common high-pressure reactor (autoclave).
The hydrogenation reactor design is mainly for the purpose to avoid explosion because hydrogen is a flammable and explosive gas.
In order to prevent the hydrogen from leaking and bursting by naked fire, the electrical parts of the hydrogenation reactor are all explosion-proof, such as the motor is explosion-proof, the heater is explosion-proof, the temperature sensor, and the pressure sensor are all explosion-proof, in order to prevent the sparking.
There is a big difference between the shaft seal of the stainless steel hydrogenation kettle and the common high-pressure reactor. The shaft seal of the common high-pressure reactor usually adopts the mechanical seal or packing seal, which usually has no big leakage under low reaction pressure, but the leakage is bigger when the pressure is high, and it will burst when the leakage reaches a certain level with the open fire, while the hydrogenation reactor adopts the magnetic coupling static seal, which is driven by the motor. The inner magnet drives the stirring shaft and stirring blade to form stirring, while the inner magnet is sealed by the sealing isolation sleeve and the reactor body as one, so there is no leakage at all.
The electrical components of the hydrogen kettle, such as platinum resistance and pressure sensors, need to be explosion-proof to prevent sparks from igniting the hydrogen gas.
The common high-pressure reactor with the explosion-proof device also has the function of a
hydrogenation kettle.
