摘要： 为了在温和条件下提高多孔介质中甲烷的储量，基于吸附⁃水合法研究了MIL⁃101(Cr)中甲烷的储存特性。首先制备了MIL⁃101(Cr)材料，然后对材料进行了表征，最后在271.15 K、0～7.0 MPa及不同含水量下进行了甲烷吸附实验。合成的材料颗粒大小均一，晶粒尺寸为100～150 nm，几乎不含杂质，孔径主要分布在1.7～3.6 nm。吸附实验结果表明，MIL⁃101(Cr)在含水情况下对甲烷的吸附量更高，且随着含水量的增加，甲烷的吸附量增大；多孔介质中水合物成核所需压力比自由体系水合物成核所需压力高，且含水量越大，临界压力越高；实验所用的MOF材料在多次再生后仍具有较好的吸附能力。研究结果对提高天然气的储量具有一定的意义。

Abstract: In order to improve the methane storage in porous media under mild conditions, the storage characteristics of methane in Mil⁃101 (Cr) were studied based on adsorption water method.MIL⁃101 (Cr) was prepared and characterized. Methane adsorption experiments were performed at 271.15 K and 0～7.0 MPa with different water contents. The particle size of the synthesized material was uniform, grain size range was 100～150 nm, and almost without impurities. The pore size was mainly distributed in the range of 1.7 nm to 3.6 nm. The results of adsorption experiments show that: MIL⁃101 (Cr) adsorbs more methane under the condition of water, and with the increase of the water content, the amount of methane adsorption increases. The pressure required for nucleation in porous media is higher than that for bulk system, and the greater the water content is, the higher the critical pressure is. The MOF material used in the experiment still has good adsorption capacity after repeated regeneration. The research results have certain significance for increasing the natural gas storage capacity.
