两种煤焦油沥青恒温热转化过程的研究

Study on the Isothermal Conversion Process of Two Coal Tar Pitches

通过对两种煤焦油沥青恒温热转化过程的研究，得出了中间相转化的特征时间和动力学参数，试验表明，在中间相产率约１５％之前，主要产生中间相小球体的生成反应，活化能较高，而后期反应活化能较低。

Through the study on the Isothermal conversion process of two coal tar pitches, the characteristic time of mesophase conversion and kinetic parameters have been obtained. Test shows that before the mesophase yield of 15% is reached, the formation reaction of small mesophase sphere occurs with high activation energy, but the reactive activation energy at later period is lower.
