Xylitol/Sorbitol Hydrogenation Reactor

The Xylitol/Sorbitol Hydrogenation Reactor is an industrial-scale stirred pressure vessel for catalytic hydrogenation run as a three-phase slurry. The liquid carries a suspended solid catalyst, and hydrogen is present as dispersed bubbles. It belongs to the Coretest industrial reactor group for chemical production. The specification table lists total volume from 2,000 liters to 30 m³, design pressure of 60 to 150 bar and design temperature up to 250 °C.

How it works

The reaction crosses several phase boundaries, so gas-liquid mass transfer governs the rate and hydrogen dispersion is the main factor. The agitator is therefore a hollow shaft with a gas induction impeller, which draws hydrogen from the headspace and releases it as fine bubbles in the liquid. Gas hold-up and interfacial area rise, unreacted gas is recirculated, and the catalyst stays in uniform suspension. Stirring speed is 0 to 350 rpm.

The shaft is driven through a magnetic coupling, which gives a zero-leakage agitator seal. The motor is explosion-proof (DIICT4), 7.5 to 90 kW. An oil jacket heats the vessel; internal spiral coils or a cooling tube condenser remove heat. Listed jacket types are conventional (full), limpet coil or half-pipe, and dimpled. The closure seals with a spiral wound metallic gasket. Standard vessel material is SS304 or SS316. Solid or clad construction is listed in SS2205, SS321, C-276, nickel, titanium and zirconium, with explosive clad steel for corrosive high pressure duty. The magnetic drive range is listed to full vacuum and 200 bar.
