Description	Natural gas is a naturally formed hydrocarbon gas mixture consisting primarily of methane, but commonly including a certain amount of carbon dioxide, hydrogen sulfide, higher alkanes and other inert gases(Baker and Lokhandwala 2008). The composition of gas delivered to commercial pipeline must be controlled to avoid undesired corrosion. For instance, raw gas usually requires treatment to reduce the $CO_{2}$ concentration to less than 2% and $H_{2}$S concentration below 4 ppm according to the U.S. natural gas pipeline specifications. Until now, processing of natural gas has been the largest industrial gas separation application. Conventional separation technologies such as amine sorption are very energy-consuming and non-environmental friendly. Ninety percent energy will be saved if applying membrane technology for removing $CO_{2}$ from the industrial streams (Leung et al. 2014). The key of this membrane process is developing high-performance asymmetric gas separation membranes—highly permeable and selective for $CO_{2}$ molecules. Polymers, inorganic materials, mixed-matrix materials and carbon molecular sieves have been processed into asymmetric membranes via different techniques. This chapter will discuss the latest progresses in design and preparation of asymmetric membranes for natural gas purification, particularly focusing on the $CO_{2}/CH_{4}$ separation.
