摘　　要：在温度 2 75 75～ 2 79 95K和压力 5 6～ 9 6MPa的静置条件下 ,测定了 14组甲烷水合物在活性炭中的生成动力学数据 (压力 时间关系 )。分析了甲烷水合物在活性炭中生成的物理过程 ,结合边界层理论和结晶学原理 ,提出了单液膜传质控制机理的生成动力学模型 ,并求得了解析解。使用Levenberg Marquardt方法拟合模型参数 。Kinetics of methane hydrate in methane/(water + active carbon) system was investigated. 14 groups of kinetic data (p-t) of methane hydrate formation in active carbon were measured in the temperature range of 275.75-279.95 K and the pressure range of 5.6-9.6 MPa. Based on the theory of boundary layer and crystallography, a kinetic model, as called single film mass transport limited model, is proposed. The analytic solution of this model was obtained. Levenberg-Marquardt method was used for fitting model parameters. A good agreement was found between model predictions and experimental data.
