Catalyst Hydrogenation Reactor

The Catalyst Hydrogenation Reactor LECHR is a stirred pressure vessel for three-phase slurry hydrogenation, where a solid catalyst is suspended in the liquid phase and hydrogen is present as gas bubbles. With several phase boundaries in the vessel, hydrogen dispersion governs mass transfer, and the mixing system sets the gas-liquid mass transfer coefficient. The standard family covers 100, 200, 500 and 1000 L at a design pressure of 150 bar and design temperatures up to 300 °C.

How it works

A hollow shaft with a gas induction impeller recirculates unused hydrogen from the headspace back into the liquid. This gives a fine dispersion of hydrogen, a large gas-liquid interfacial area, higher gas hold-up and mass transfer, and uniform suspension of the catalyst. The shaft is driven through a zero-leakage magnetic coupling: fully sealed, with low energy cost and long bearing life, available from full vacuum to 200 bar, with a cooling jacket for high temperature service. The motor is explosion-proof, DIICT4, from 7.5 to 90 kW, for stirring speeds of 0 to 350 rpm.

Heating is by oil jacket of conventional, limpet coil or half-pipe type; full, half-pipe and dimpled jackets are offered. Cooling is by internal spiral coils or a cooling tube condenser. The vessel is sealed with a spiral wound metallic gasket. Head type can be semi-elliptical, dished, hemispherical or flat.
