Kinetics of methane hydrate formation in active carbon

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.
