The effective development and reasonable utilization of energy are the focus of the national sustainable development problems, which occupies an important position in the development of the national economy. Oil shales, as an important supplement and alternative energy, with its huge storage, diversified utilization level, has attracted worldwide attention. In order to take advantage of this energy reasonablely and effectively, basic research must be conducted. The physical and chemical structure of oil shale played a key role in oil shales’ efficient utilization and development. The advanced testing techniques and methods provided convenience for the physical chemistry structure of the oil shale. On the basis of that, the macromolecular network pyrolysis model was better reasonable to simulate the process of pyrolysis reaction.The carbon atom chemical structure of four Wangqing mining oil shale was characterized by the 13C-NMR techniques. The chemical structure parameters of cluster, such as average number of carbons, aromatic carbons, aliphatic carbons and aromatic rings of oil shales, have been calculated by13 C solid-state NMR. To obtain the yields of pyrolysis products, TG-FTIR experiments were used for oil shale pyrolysis. Combined with the cluster chemical structure parameters of the sample, the release process of pyrolysis products was simulated by FLASHCHAIN. The simulation results were in good agreement with the TG-FTIR experimental data, which demonstrates the rationality of model prediction. Therefore, this article through the research of oil shale pyrolysis process light gas, combined with the heat release volatile reaction FLASHCHAIN modoel to predicted pyrolysis FLASHCHAIN model is applicable to Wangqing oil shale, in order to reveal the macromolecular relationship between structure and reactivity and reveal reaction mechanisms of pyrolysis oil shale reveal this card from nature.In the end, the theoretical research can provide theoretical basis for rational exploitation and utilization of oil shales.
