Solid fossil fuels still support the development of the energy and chemical industry. The clean and efficient utilization of solid fossil fuels can effectively alleviate the problems of energy shortage and environmental pollution. An in‐depth understanding of the kinetic process, models, and mechanism of pyrolysis of solid fossil fuels is also of great significance for the exploration and utilization technologies of petroleum resources. Thermogravimetric analysis is an effective method to study the pyrolysis process and kinetics with the advantages of high sensitivity, repeatability, and reliability for data acquisition. Researchers have conducted a lot of research on the thermogravimetric kinetics of solid fossil fuels in recent years, but there is a lack of systematic summary and comparison of kinetic methods, research progress, and trends. Therefore, a comprehensive study on pyrolysis kinetic principles, methods, and models of solid fossil fuels by thermogravimetric analysis is carried out in this paper. The influencing factors of pyrolysis kinetics of solid fossil fuels using thermogravimetry are elaborated and discussed in detail. This study also provides progress in recent years and prospects of thermogravimetric kinetics of solid fossil fuels. It is expected that this paper can provide certain technical support and theoretical guidance for the research on pyrolysis kinetics based on thermogravimetric analysis, and the exploration and development, clean, and efficient utilization of solid fossil fuels.

“…Oil shale after retorting is the solid waste residue left after oil shale is subjected to low-temperature retorting to obtain shale oil. Although the ash content is higher than that of oil shale, there is still a small amount of organic compounds remaining, and it has certain ability to absorb oxygen and release heat at low temperatures. − Trikkel and Han et al , believe that oil shale can continue to be burned and utilized after dry distillation.…”

The spontaneous combustion of underground minerals causes huge property losses and ecological damage. Coal and oil shale are co-associated minerals in the Fushun West Mine, and both have the ability to undergo oxidative spontaneous combustion. To study the effect of microstructure changes on the macroscopic gas product concentration during the mineral oxidation spontaneous combustion process in the Fushun West Mine, this study used a high-temperature temperature-programmed test to obtain the change trend of gas product concentration in different oxidation stages of minerals. Using Fourier transform infrared spectroscopy technology, the changes in active functional groups of surface molecules during the process of mineral oxidation and spontaneous combustion were identified. Finally, using the gray correlation degree, correlation analysis between the concentration of gas products and the concentration of active functional groups in different oxidation stages was carried out. The key reactive functional groups affecting mineral spontaneous combustion were identified. The essential reason for the change in the gas product was revealed.

“…Most of shale oils (SOs) are derived from oil shale pyrolysis; − long-chain n -alkanes and n -alkenes in the shale oil can be used to produce high-quality paraffin, which can also be processed into liquid fuel . After extracting or removing the aliphatic hydrocarbons by solvent extraction, heteroatom-containing aromatic compounds that remained in a polar solvent, such as phenol (P), should neither be ignored nor wasted, since they are important components in shale oil and significant chemicals. , Furthermore, effectively separating Ps from a SO and its derivatives facilitates the smart application of the shale oil.…”

Several liquid deep eutectic solvents (DESs) at room temperature were screened and used to extract phenols from an acetonitrile-extractable portion (ANEP) of the oil from oil shale pyrolysis. Among choline chloride (CC)/ethylene glycol (EG) with lowest viscosity and neutral oil entrainment (molar ratio = 1:3) was selected as an optimal DES for isolating phenols from ANEP. As a result, the CC/EG-extractable portion contains 56.7% of oxygen-containing aromatics, among which phenols account for 75.1% by magnetically stirring the isometric mass mixture of ANEP and the CC/EG at room temperature and 500 rpm for 0.5 h. Intermolecular interaction energy and type between different DESs and solutes were calculated by molecular dynamics simulation, independent gradient model analysis, energy decomposition analysis based on the force field, and electrostatic potential analysis to uncover the mechanism for the priority separation of phenols. The result shows that the DES that contains polar HBD with lower viscosity and carbon number and asymmetric HBA with shorter alkyl chains, e.g., CC/EG, could strongly interact with phenols by the strong hydrogen bond, X-H···π and/or cation/anion···π compared to other aromatics.
