| The formation and dissociation reaction rates and their kinetic behavior of propane gas hydrate (PGH) within the well-defined sediment particle's packing structures were experimentally investigated in this work by using a multi-phase heterogeneous reaction system, consisting of propane gas (g), water (l), PGH (s) and sediment particles (glass beads) (s). This work was carried out under the formation conditions of P = 0.427 MPa and T = 273.5 K, and under the dissociation conditions of P ≤ 0.168 MPa and T = 273.5 K.; A new designed, isothermal, and packed bed batch reactor was used for the kinetic analysis of the above defined PGH reaction system under the smooth operating conditions, yielding the satisfactory, reproducible material balance. Quantitative overall reaction rates of PGH formation and dissociation were derived and orders of the above reactions were experimentally obtained. |
