“…The average activation energy corresponding to the OM pyrolysis process of CK oil shale is estimated to be 211.5 ± 4.7 kJ mol −1 . This value is consistent with the energies obtained during the type I kerogen pyrolysis of the Green River, Colorado and Huadian oil shales which were evaluated to be 201, 219.4 and 231 kJ mol −1 , respectively (Campbell et al 1978;Han et al 2015;Maaten et al 2017).…”

“…A thermocouple was used to measure the temperature of the sample center. For each test, 50 g of oil shale was loaded into the retorting reactor, which was then slowly heated from room temperature to the pyrolysis temperature at a heating rate of 2 °C·min –1 to guarantee uniform temperature distribution in the sample. , Upon reaching the temperature, the reactor was quickly cooled to room temperature, and then the gas, shale oil, and semicoke were weighed. Thermal bitumen was extracted from the semicoke by using the Soxhlet extractor with chloroform solvent (CHCl 3 ) at 65–70 °C for 48 h. The chloroform solution was finally evaporated to obtain thermal bitumen and then maintained in a cold storage for further analysis (Figure ).…”

“…To obtain thermal bitumen, 30 g of oil shale sample was loaded into the retort. Then, the reactor was slowly heated from room temperature to the pyrolysis temperature at a heating rate of 2 °C/min to guarantee that the whole sample was evenly heated. , When the final temperature was reached, the reactor was rapidly cooled to room temperature. The thermal bitumen was then extracted from semi-coke by a Soxhlet extractor with chloroform (CHCl 3 ) as the solvent at 65–70 °C for 48 h. The chloroform solution was finally evaporated in a rotary evaporator to obtain thermal bitumen, which was then stored in cold storage for further analysis.…”
