A large amount of boil-off gas (BOG) is generated during the storage and transportation of liquefied natural gas,which results in not only resource wastage but also potential safety hazards.Therefore,the liquefied natural gas-adsorbed natural gas (LNG-ANG) coupling technology has attracted increasing attention from researchers.Developing efficient and stable adsorbents is the core key to the practical application of this technology.In view of the requirements of LNG-ANG coupling technology for adsorbents, this paper summarizes the research progress of metal-organic framework materials (MOFs) in methane adsorption at low temperature (about 159 K).By comparing the advantages and limitations of adsorption at low temperatures (159 K) with at room temperature (298 K),several MOFs materials that are more conducive to the adsorption and storage of methane are listed,including flexible MOFs,highly porous MOFs,hierarchically porous MOFs and MOF composites,aiming to offer references and guidance for the practical industrial application of MOFs in LNG-ANG coupling technology.
