Abstract
The extraction of the organic matter (OM) from oil shale (OS) can be achieved by several processing techniques. Normally, these techniques can remove high proportion of the organic material contained in oil shale. In this work, organic solvents extraction experiments were implemented to investigate the effect of various parameters on Jordanian El-Lajjun oil shale extractability. Results indicate that the approximate organic matter content in studied El-Lajjun oil shale is 17.48%, and 75% of OS sample particles diameters are less than 270 μm. The grain size has minor effect on shale oil extraction via organic solvents. Among eleven solvents used, the highest yield is obtained via the tetrahedrofuran (THF), whereas, with the use of solvent mixtures, the highest bitumen yield is obtained through the mixture of THF and toluene. The solvation variability is related to mode of extraction and various physicochemical factors such as extraction temperature, pressure, solvent type and mixing time, which result in different OM yield. The results indicate that the solvent extraction could be potential for shale oil extraction from Jordanian El-Lajjun OS under certain conditions of temperature, pressure and solvent type used.

Summary
Oil shale (OS) deposits are widely distributed in the world. Oil shales are sedimentary rocks contain hydrogen rich organic matter (OM) that is known as kerogen and bitumen [1]. (2015) Shale Oil Solvent Extraction of Central Jordan El-Lajjun Oil Shale. The extraction of shale oil from its sources is usually undertaken above ground (ex-situ processing) and some recent technologies perform this in-situ. In both cases, the immature kerogen is converted to synthetic shale oil and OS gas. Those evaluation studies aimed to investigate the suitability of the well known OS processing methodologies to the use, processing, and extraction of shale oil from the Jordanian oil shales, e.g.
