中文摘要：
利用自主设计的页岩中气体吸附解吸实验装置，在不同温度和压力条件下研究CO2在不同页岩中的吸附解吸性能。结果表明：CO2在页岩上的等温吸附曲线属于典型的I型等温曲线，可采用Langmuir模型对吸附及解吸数据进行拟合；相同温度下，CO2在页岩中的吸附量随着压力的升高而增大；相同压力下，CO2在页岩中的吸附量随着温度的升高而减小；相同温度压力条件下，CO2解吸过程中存在解吸滞后现象，且解吸附曲线表征的最大吸附能力低于吸附曲线表征的最大吸附能力；CO2在页岩上最大吸附量随有机碳含量增加而增大，随石英含量增加而减小。
英文摘要：
Laboratory shale cores adsorption and desorption experiments with CO2 were carried out using the self-developed experimental device of gas adsorption and desorption on shale under different pressure and temperature. The results show that the adsorption isotherms of CO2 on shale are the representative type I curves, and the adsorption and desorption curves are in line with the Langmuir model. The adsorption capacity of CO2 on shale increases with the pressure increasing under the same temperature, while it decreases with the temperature increasing under the same pressure. At the same temperature and pressure, the desorption curves exhibit hysteresis phenomenon, and the maximum CO2 adsorption capacity characterized by the desorption curve is less than that characterized by adsorption curve. The maximum CO2 adsorption capacity increases with the total organic carbon （TOC） content in shale increasing and decreases with the inorganic mineral content increasing.
