Plate-type MMRs

In plate-type MMRs, the microchannels for catalyst deposition are fabricated on a porous silicon or stainless steel (i.e., SS 316L) plate, while the membrane layer is deposited on the back of the plate to perform separation (membrane/catalyst plate) as shown in Figure 8.1(a). In some cases the membrane layer, which also shows catalytic activity, is deposited on the wall of the microchannels for simultaneous reaction and separation...

A distinctive feature of microreactors is the microchannels for fluid flow. MMRs are mainly characteristic of such microchannels with anchored catalysts for reactions and miniature membranes to perform separation, which are formed on the porous ceramic or metal supports. Based on the configuration and architecture of the reactor, MMRs can be classified into two categories plate type and tubular type.
