Pre-saturation in multiphase fixed-bed reactors as a method for process intensification/reactor minimization

The pre-saturated-one-liquid-flow (POLF) technology, in which multiphase reactions are carried out over a stationary (fixed-bed) catalyst in the presence of a single liquid phase previously saturated with gas, permits a significant increase in the reactor productivity (in some cases up to 100 times). The POLF technology can provide an exceptional decrease in the size of newly constructed plants as well as a remarkable enhancement of production by revamping the existing trickle-bed or bubble column reactors.
