摘要

Microchannel reactors usually have some microchannels with characteristic sizes (i.e.,between 1 and 1000μum).Small channel size and diversity are usually patterned in a microchannel reactor,and these features increase the surface area-to-volume ratio and driving force for heat and mass transport.Microchannel reactors are widely used in the petrochemistry,aerospace,electronics,information technology,and automotive industries,among others.According to the geometric shape of microchannels,a microchannel reactor can be classified as parallel,curved,micro-pin-fin array,bionic,or 3D network type.This review summarizes the fabrication methods of microchannel reactors,including traditional mechanical processing,chemical etching,electroforming injection molding technology,non-traditional machining,and sintering.It also presents the various applications of microchannel reactors in catalytic reactions,heat transfer,mixing,and other areas.Finally,this review describes the development and application prospects of microchannel reactors.
