In order to utilize natural gas (NG), one of the clean energy sources in next-generation, as a fuel for vehicles, it is important to store natural gas with high density. To store NG by adsorption (ANG) at room temperature and at relatively low pressure(35~40 atm) is safe and economical compared with compressed NG and liquefied NG. However, so far no adsorbent is reported to have adsorption capacity suitable for commercial applications. Nanoporous materials including metal-organic frameworks can be potential adsorbents for ANG. In this review, physicochemical properties of adsorbents necessary for high adsorption capacity are summarized. Wide surface area, large micropore volume, suitable pore size and high density are necessary for high energy density. Moreover, low adsorption-desorption energy, rapid adsorption-desorption kinetics and high delivery are needed. Recently, various efforts have been reported to utilize nanoporous materials in ANG, and it is expected to develop a nanoporous material suitable for ANG.

  26. '천연가스 저장'이라는 용어는 여러 저장 방법을 이용한 천연가스라는 물질을 저장한다는 개념이 강하며 흡착은 흡착제 표면에 흡착되는 현상을 강조한 용어이며 본 총설에서는 두 용어가일부 혼용되었으나 저장은 이용 측면에서 주로 사용하였고 흡착은 물리적 현상을 설명하거나 물리량을 설명하는데 주로 사용되었음

  30. 본 총설에서는 천연가스(NG)와 메탄을 일부 혼용하였는데 천연가스는 주로 상업적으로 저장할 대상물질로 볼 수 있고 메탄은 천연가스 대신에 주로 연구의 편의를 위해 사용함. 메탄이 흡착/저장 될 수 있는 경우에 에탄 등의 천연가스의 다른 성분의 흡착/저장은 매우 용이하기에 연구는 보통 메탄으로 수행함
