报道了甲烷水合物分解动力学的实验数据。对Kim等人（1987）使用的等温/等压半间歇搅拌罐反应器进行了改进，以包括在线粒度分析仪。实验在274.65 K至281.15 K的温度范围内和3.1至6.1 MPa的压力下进行。Clarke和Bishnoi（1999，2000）的模型用于确定内在速率常数。结果表明，甲烷水合物分解的活化能为81 kJ/mol，分解的本征速率常数为3.6 × 10 ~（4）mol/m ~（2）Pa·s。
Experimental data on the kinetics of methane gas hydrate decomposition are reported. The isothermal/isobaric semi-batch stirred-tank reactor, used by Kim et al. (1987), was modified to include an on-line particle size analyzer. The experiments were conducted at temperatures ranging from 274.65 K to 281.15 K and at pressures between 3.1 and 6.1 MPa. The model of Clarke and Bishnoi (1999, 2000) was used to determine the intrinsic rate constant. It was found that the activation energy for methane hydrate decomposition is 81 kJ/mol and the intrinsic rate constant of decomposition is 3.6 x 10(4) mol/m(2) Pa.s.
