摘　　要：运用一个基于 Ono- Kondo晶格理论模型的新方程 ,描述了甲烷在狭缝状微孔内的超临界温度高压吸附 .为检验理论模型 ,用体积法测量了压力为 0～ 6MPa范围内甲烷在高比表面活性炭上的 Gibbs吸附量 .对比模型与实验结果显示 。A new equation describing the adsorption of methane above the critical temperature on micro porous adsorbents was presented. The equation is based on the Ono Kondo lattice theory for adsorption in slit like porces. Linear regression of the experimental data of methane adsorption above the critical temperature to this new equation based on the lattice theory was done. The excess adsorption measurements in the 0～6 MPa presure range on high BET surface areas activated carbon were carried out using a volume method to validate the new model. The agreement between the prediction of the new model and our experimental data is quite good. It is shown that this new model is capable of describing high pressure adsorption of supercritical methane in a certain range of temperature and pressure.
