This study evaluates the possibilities to produce new materials, starting from Moroccan oil shales, for different applications. More specifically, the authors aimed to demonstrate that the organic fraction of the oil shales could be used as a precursor of carbon foams and graphitizable carbons, after appropriate chemical treatments resulting in the "maturation" of this organic phase. First, the researchers studied the optimization of experimental conditions and the identification of various parameters influencing the yield and composition of oils obtained by the supercritical extraction of Moroccan oil shale. The effect of various experimental parameters, such as mineral matter, thermal treatment temperature (T), treatment duration (t) and solvent type, was studied. The experimental results obtained show clearly that the organic matter contained in the Moroccan Tarfaya oil shale (sub-layer R 3 ) can be recovered by phenol under the following optimal conditions: T = 390 °C, t = 2.5 hours using phenol as a solvent with an amount of 15 g for each 10 g of sub-layer R 3 carbonate-free oil shale (RH) . The results reveal that the yield and composition of the oil obtained by extraction with phenol is markedly different from those obtained by extraction with toluene, quinoline or withoutThe effect of various parameters on the supercritical extraction of Moroccan oil shales … solvent. Furthermore, the phenol has a very significant role in increasing the recovery yield and the degree of maturation of the obtained oil. It was shown that phenol was a suitable extraction solvent to produce graphitizable carbon at a relatively low temperature, below 1800 °C.

“…An increase in the amount of hydrocarbon gases has a positive effect on the quality of the resulting product. 68.6% of the products was extracted by SWG from Moroccan Tarfaya oil shale at a temperature of 390 °C and an extraction time of 150 minutes [96]. Chham et al [97] used different solvents and wastewater from the olive oil production plant under sub-and supercritical conditions.…”

“…In addition to using water as a solvent, several studies have employed CO 2 , aromatic solvents (such as benzene, toluene) and ethanol for extraction [96,97,101,102]. CO 2 as a cheap solvent is very interesting in supercritical extraction, and the main efforts of researchers in recent years have been directed at studying the wettability effect of coal and oil shale.…”

A review of literature data on the processing of solid types of combustible fossils into liquid fuels and chemical products has been carried out. The reserves of solid fossil fuels far exceed the natural resources of oil and gas, so the development of methods for processing solid fossil fuels into chemical products and liquid fuels is an urgent task. The main methods of processing coal and oil shale (OS) are reduced to pyrolysis and supercritical gasification. Pyrolysis is preferred for processing oil shale into shale oil, and currently a promising method for processing coal is extraction with supercritical solvents such as water and CO 2 at temperatures up to 900 °C and in some cases with the addition of a catalyst. For oil shale, the gasification process, like pyrolysis, is carried out under milder conditions, since the mineral part of oil shale contains trace elements that act as catalysts, and the structure of the organic part of oil shale is more similar in composition to oil.

This study focuses on investigating the effect of various solvents on the supercritical extraction of organic matter from Moroccan oil shales, with the goal of determining the optimal operating conditions that result in a high yield of high-quality oil rich in aromatic compounds. The results of this study demonstrate that the extraction yield and quality of the extracted oil heavily depend on the chosen operating conditions for supercritical or subcritical extraction of organic matter from oil shale. Additionally, the study found that phenol can effectively degrade oil shale and enable extraction of nearly all the organic matter, even under mild conditions (T = 390˚C, P = 1.2 MPa, Time = 2.5 h. Furthermore, the oils obtained through this extraction process are of high quality, with a rich content of maltenes, and a higher concentration of aromatic compounds and lower levels of sulfur than those obtained using other solvents.
