The porous structure of oil shale plays a vital role in heat transfer and mass transport of its pyrolysis, particularly for the flow behavior of shale oil and gas during in-situ conversion. It is essential to clarify the pore evolution and give a mathematical description of the complex pyrolysis. In this study, the effect of temperature (100–800°C) on Huadian oil shale pyrolysis, and the creation...
Oil shale pyrolysis is normally extremely complicated because many reactive processes simultaneously occur and different products are therefore continuously generated and serve as a new reactant, as a multi-stage processes with competing or parallel reactions. To probe deeply into the pyrolysis kinetics of Huadian oil shale, we have employed multi-stage parallel reaction model and bi-Gaussian distribution...
In this study, the topochemical reaction strategy, utilizing Huadian oil shale to produce shale gas, liquid, and solid residues, has been demonstrated. Thermogravimetric analysis, Fourier transform-infrared spectroscopy, X-ray diffraction, gas chromatography–mass spectrometry, and scanning electron microscopy were performed to characterize the products obtained at different temperatures. Furthermore,...
