摘　　要：将等温动力学方程应用于COREX用煤焦油析出反应过程中,得出COREX用煤焦油析出反应过程的动力学参数,并进一步得到COREX用煤焦油析出速率常数与温度及其活化能与温度的定量关系式。利用得到的动力学参数计算出的理论焦油产率与试验结果基本吻合。Kinetic parameters in the reaction process of separating tar from coals used in COREX process were obtained by the application of isothermal kinetics equation.Afterwards,quantitative relations of the speed constant,the activation energy and the temperature were determined.Moreover,theoretical yield of tar wels was calculated by kinetics method.Compared to the real yield of tar in the test,it is found that the tendency is accordant.
