Description

In this article, recent topics of enzyme membrane reactors are reviewed. Membrane reactors can be classified into five types, according to whether the enzymes are free or immobilized, and whether the driving force for the mass transfer is pressure or diffusion. The functions of membranes of each type of the reactors are discussed and some typical reactors and reaction systems are described. The relative merits of pressure-driven reactors or reactors in an ultrafiltration mode in which the mass transfer occurs by pressure-driven convection and diffusional reactors in which the mass transfer occurs by diffusion are extensively discussed on the basis of the reactor performance. Previously published theoretical and experimental results and new additional calculations show that from the viewpoint of productivity and operational problems with reactors, reactors in an ultrafiltration mode are not necessarily superior to diffusional reactors.
