Hydrogenation

Introductions

The hydrogenation system usually involves a three-phase slurry, the solid catalyst in slurry phase and the hydrogen bubbles as the gas phase. As there are a number of phase boundaries the mass transfer, and especially the hydrogen dispersion, is a very factor. The mixing system that is employed in the reactor influences the mass transfer coefficient of the gas-liquid transfer greatly.

The HUIXIN impeller uses the acceleration of the liquid phase over the blades to locally reduce the pressure and thereby induces a flow of gas through the hollow shaft from headspace; the gas flow rate and the impeller speed become dependent in such gas induction impeller systems. The critical speed at which the onset of the gas induction occurs may be considered as the first step in design. The induced gas is well dispersed into the reaction bulk thereby improving the gas-liquid mass transfer rates.
