| Abstract: | Taking extraction humus acid from lignitous coal for an example,the author analyzed features of humus acid structure by using 13C CP/MAS NMR.Combining element,the author analyzed and built chemical structure model.According to comparison of simulated spectrum and experimental spectrum,the author got final structure model.Then,the author described the whole process of non-isothermal pyrolysis from low temperature to high temperature by using DAEM（activation energy distribution model）.Through dynamical analysis,the author combined structure model and formation mechanism of methane,which showed that formation of methane includes 6 different reactions. |
