Sorbitol Hydrogenation Reactor

The sorbitol hydrogenation reactor is a gas-liquid-solid three-phase high-pressure vessel in which an aqueous glucose solution is catalytically hydrogenated under high pressure over a Raney nickel or ruthenium catalyst to produce sorbitol. It is core hydrogenation equipment in the sugar alcohol industry, available as batch reactors (mainstream), semi-continuous, and continuous units.

Magnetic Drive Device for Sorbitol Reactor

The mainstream route to sorbitol is the high-pressure hydrogenation of glucose, a gas-liquid-solid three-phase high-pressure hydrogenation duty (hydrogen, glucose solution, and nickel-based catalyst). Hydrogen is flammable and explosive, so the reliability of the agitator seal is critical; industry generally uses a magnetically driven agitator on the vessel top, using static seals to eliminate the risk of hydrogen leakage from the shaft seal.
