Membrane reactors (MRs) are systems in which a membrane separation process is combined with a chemical (catalytic) reaction. Because there are different ways to combine a catalyst with a membrane in order to have a synergic effect on the entire process, there are numerous possible categorizations of these systems. Some useful classifications are presented to highlight the advantages and still-existing limitations of MRs in comparison with traditional reactors. Classification can be based on the role of the membrane in the catalytic process (catalytically active or providing only a separation function), the type of transport through the membrane (extractor-, distributor-, and contactor-type MRs), the natures of the membrane material (organic or inorganic) and catalyst (artificial or biological). Applications of MRs in high-temperature reactions using inorganic membranes and in low-temperature MRs using polymer membranes are presented, as well as large-scale applications in membrane bioreactors for wastewater treatment.
