摘　　要：东胜长焰煤在实验室低温干馏炉经过恒速升温提质和恒温提质制备17个提质煤样。所有提质煤样按国标进行镜质体反射率的煤岩分析。定义以镜质体反射率表征的提质转化率。通过恒速升温提质和恒温提质的动力学方程分别计算各自方法的指前因子和活化能。这为解决提质煤化的T-t-R0热动力学关系提出新的分析思路和方法。提质煤化T-t-R0热动力学的成功应用取决于变质煤化与提质煤化的相互借鉴和相互校验。Artificial pyrolysis of Dongsheng long flame coal has been conducted in the laboratory’s retort through constant heating speed or isothermal conditions. Total 17 upgraded coal samples are prepared and tested for vitrinite reflectance. A conversion rate characterized by vitrinite reflec-tance has been defined. The pre-exponential factors and activation energy of both constant heat-ing speed and isothermal conditions are calculated in order to solve T-t-R0 coalification thermo-dynamic relationship of artificial pyrolysis. The successful application of T-t-R0 coalification thermodynamics depends on the mutual reference and mutual verification of nature metamor-phism and artificial pyrolysis.
