Research Progress on Low-Temperature Adsorption of Methane by MOFs Based on LNG-ANG Coupling
液化天然气在储运过程中会产生大量蒸发气,不仅会造成资源浪费,而且存在安全隐患.因此,液化天然气-吸附天然气(LNG-ANG)耦合技术受到了越来越多研究者的关注.开发高效稳定的吸附剂是该技术应用的关键.基于LNG-ANG耦合技术对吸附剂的要求,综述了金属有机框架材料(MOFs)在低温(约159 K)下吸附CH4的研究进展,对比分析了其与常温(298 K)吸附在CH4吸附与存储中的优势与不足,并列举了几类更有利于CH4吸附与储存的MOFs材料,包括柔性结构的MOFs、高度多孔的MOFs、多级孔MOFs和MOFs复合材料,以期为MOFs在LNG-ANG耦合技术中的实际工业应用提供指导.
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.
