Micro-reactor (MR) technology is known as an alternative technique for producing materials in a more sustainable way. The advantages of micro-reactors and membrane separation which are combined in membrane micro-reactors (MMR) listed as improved heat and mass transfer, high surface area to volume ratio, enhanced catalytic efficiency with no equilibrium limitation, flexibility in reactor design, a short distance of molecular diffusion as well as high operational safety. The restriction of low production capacity of micro-reactors can be easily solved by using parallel micro-channels in a reactor chip. This mini-review represents firstly the definition of micro-reactors as well as the advantages and disadvantages of membrane micro-reactors. Furthermore, the theoretical basics of membrane micro-reactors and their fabrication methods are presented. At last, the application of catalytic membrane micro-reactors in different processes is given especially in biofuel production. The achieved results of previous researches for hydrogen and other fuels production show better performance of catalytic MMRs in terms of reaction conversion and coke deposition compared with convectional reactors at the same reaction conditions.
