“…Besides retorting, solvent extraction of organic matter from oil shale was reported . Production of shale oil as a substituent for crude oil is an active research area and has received important attention in the last few years . Although thermal retorting is the most efficient method to extract organic matter, it has two main drawbacks: (a) high emission of N and S gases and (b) large consumption of water .…”

Organic matter recovery by solvent extraction has been the focus of numerous research area. In this work, recovery of organic matter from oil shale was evaluated by using Soxhelt extraction. Better oil extraction was reported after preheating of the shale to 300°C in inert atmosphere. The extracted oil was fractionated to asphaltenes, aliphatics, aromatics, and polar compounds with percentages of 4.2%, 52.6%, 20.9%, and 22.3% respectively. Compared with thermal retorting, the oil obtained by solvent extraction has higher aliphatics and polar compounds. Following a proper design of experiments, oil recovery was correlated with the following experimental factors:Extraction OM% = 7.39 + 2.23 Temp + 0.20 Mass – 0.34 PS − 0.022 Ext Time + 0.13 Temp × Mass – 0.28 Temp × PS – 0.30 Mass × PS. The results indicated that preheating temperature and mass of oil shale were positively correlated with oil extraction. However, particle size/preheating temperature and mass/particle size were negatively interacted for better oil extraction. Optimum conditions for oil recovery were accomplished using tetrahydrofuran at solid‐to‐liquid ratio of 50:1 g/mL, particle size 200−250 μm, and extraction time of 8.0 hr.

“…In terms of characterizing and understanding the mineralogy and geochemistry, a number of techniques have been traditionally used such as X-ray diffractometry, scanning electron microscopy, Rock Eval analysis and gas chromatography [4][5][6]. Similarly, infrared spectroscopy (IR) is another method that has been used for a number of years to provide chemical information and assess the structural properties of a wide range of inorganic and organic materials [7].…”

“…During the past years, a number of studies have been focused on the understanding of shale systems and their behaviors under hydraulic fracturing conditions [27][28][29][30][31][32]. In particular, the analysis of structural properties of the shales [27,31,32] and the shale-CO 2 /H 2 O interaction [30,33] was performed.…”

“…In particular, the analysis of structural properties of the shales [27,31,32] and the shale-CO 2 /H 2 O interaction [30,33] was performed. These studies showed that no two shales are alike, but many properties of the shales are often determined by inorganic matter (e.g., SiO 2 ).…”
