摘要
研究了非纯水体系H2O-H2O2-CO2中CO2气体水合物分解的动力学,测定了高压低温条件下CO2气体水合物分解过程的液相组成.依据实验数据建立了CO2气体水合物分解动力学模型,模型计算值与实验值吻合良好.确定了3个温度下气体水合物分解的速率常数,计算得出CO2气体水合物分解的活化能为97.17kJ/mol.
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.
