Data for: Influence of solvents on pore structure and methane adsorption capacity of extracted lacustrine shales: An example from a Chang 7 shale sample in the Ordos Basin, China

To explore the influence of solvents on the pore structure and methane adsorption capacity of extracted shale, a sample of the Chang 7 shales from the Ordos Basin, China is extracted using acetone, tetrahydrofuran (THF), carbon disulfide (CS2), and benzene, respectively. Low pressure gas (CO2 and N2) adsorptions and methane adsorption experiments were carried out on the studied samples before and after extraction.

为探究溶剂对抽提后页岩孔隙结构及甲烷吸附容量的影响，本研究以中国鄂尔多斯盆地Chang 7段页岩为研究对象，分别采用丙酮（acetone）、四氢呋喃（tetrahydrofuran, THF）、二硫化碳（carbon disulfide, CS₂）与苯（benzene）对其开展抽提处理。随后，分别对抽提前后的页岩样品开展低压气体（二氧化碳carbon dioxide, CO₂、氮气nitrogen, N₂）吸附实验及甲烷吸附实验。
