Among separation methods, specially gas separation, the membrane separation process has been developed by researchers in last decades due to their advantages such as lower energy consumption, possibility of separation processes and operation in environmental temperature, simple accessibility of the separated phases, artless operation and installation and no requirement to use chemical materials for separation which results in environmental problems due to consumption ofchemical materials.Although, carbon membranes in membrane based gas separation processes have been attended by researchers because of their suitable permeability and selectivity and high stability in corrosive and elevated temperature environment, they suffer from some problems such as frangibility and high cost fabrication that donʹt permit their application in extreme conditions. Carbon membranes are one type of porous inorganic membranes. This article reviews the fabrication methods of carbon membrane and considers its most effective process parameters. Therefore, at first, this paper reviews the fabrication steps of carbon membranes, i. e., precursor selection, polymeric membrane preparation, pretreatment of the precursor, pyrolysis process and post-treatment ofpyrolyzed membrane and then introduces the application of carbon membranes in gas separation processes. Finally, the advantages and disadvantages of carbon membranes are discussed
