摘　　要：提出了喷雾反应器中甲烷水合物的形成机理,并引入传质对水合反应影响的有效因子等参数,得到了喷雾法生成水合物的改进动力学方程。通过实验验证,实验数据与模型计算数据基本吻合,平均误差为4.63%。方程回归得出甲烷水合物表观活化能(Ea)为54.25 kJ/mol,根据文献结果,说明喷雾反应器中甲烷水合物生长过程由表面反应所控制。Mechanism of methane hydrate formation in a spraying reactor was proposed, and a modified kinetics equation of methane hydrate formation was established by introducing of the correction factors such as the coefficient that mass transfer affects hydration. A comparision between the calculated and experimental data indicated that the average deviation was 4.63%, which validated the model. The apparent activation energy of methane hydrate growth kinetics was regressed to be 54.25 kJ/mol^-1 , which showed that methane hydrate formation was controlled by the hydration in the spraying reactor according to the results of literature.
