Abstract: In order to develop a new method for separation of peroxide hydrogen and water system by gas hydrate, the decomposition kinetics of gas hydrate formed from H2O-H2O2-CO2 system was studied. Solution compositions in the decomposition process of CO2 gas hydrate were measured at high pressure and low temperatures, 273.15, 274.15 and 276.15 K. Based on the experimental data, the decomposition kinetics model of CO2 gas hydrate in this ternary system was established. The calculated values were in good agreement with the experimental data. The decomposition rate constant of CO2 gas hydrate decomposition reaction was determined at the above temperatures. The activation energy of decomposition reaction of CO2 gas hydrate was 97.17 kJ/mol.

Key words: gas hydrate, carbon dioxide, peroxide hydrogen, decomposition kinetics, rate constant
