Biogas is a renewable fuel source of methane that can be used as energy for vehicles after a purification process to remove impurities (Biogas upgrading and cleaning). However, removal of CO 2 from methane is one of the critical steps for biogas upgrading and is limiting its commercial application. An overview of the materials in technologies of separation (membrane) and sorption (sorbents) know-how, including chemisorbents and physisorbents, has been made with a particular emphasis on biogas upgrading. The alternative properties and possibilities of different technologies and materials for CO 2 separation, including alkanol amine, solid alkanol amine, zeolites, carbonaceous, metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), and membrane applied for purifying raw biogas (upgrading) to produce bio-methane and on the other hand, to reduce CO 2 emission from fossil fuel are discussed in this review.
