Abstract

Metal-organic frameworks (MOFs) are an emerging class of novel adsorbents for natural gas storage and can store natural gas at moderate temperature and pressure with high energy density. To select the suitable MOFs for natural gas storage, the effect of isosteric heat of adsorption, the types of interaction between adsorbents and adsorbates (electrostatic and Van der Waal interaction) and the flexibility of framework of existing MOFs on working capacities are analyzed. It can be found that MOFs with moderate interaction with methane and high density have the greatest working capacities in natural gas storage. Additionally, the flexibility characteristic of some frameworks enables those MOFs to have a high working capacity because there is a dramatic decrease in the amount of gas in pressure change. Furthermore, the factors that affected the practical use of MOFs, namely thermal property, mechanical stability, and impurities in natural gas, are discussed.
