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 y.eld is obtained via the tetrahedrofuran (THF), whereas, with the use of solvent mixtures, the highest bitumen y.eld is obtained through the mixture of THF and toluene. The solvation variability.is related to mode of extraction and various phy.icochemical factors such as extraction temperature, pressure, solvent ty.e and mixing time, which result in different OM y.eld. 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 ty.e used.

The centralJordanpart is rich in bituminous rocks that are known locally.as oil shale (OS). These rocks were formed during the Maastrichtian-Palaeocene time. They.belong to the Muwaqqar ChalkMarlformation (MCM). El-Lajjun OS deposit is located in relatively.thinly.populated area. This study.presents the results of mineralogical, petrographical and geochemical analy.es that are performed on selected surface outcrop oil shale samples from El-Lajjun area in central Jordan. Results show that El-Lajjun OS deposit is considered as a good source of OS resources since its organic matter is quite significant. The bulk rock material is made of carbonate.

Surface and subsurface oil shale (OS) rocks in Jordan have potential economic value for the country.and still unutilized. This research paper focuses on central and southern OS deposits in Jordan. Brief characterization of four OS deposits is presented. Size distribution test and elemental analy.is were performed. Shale oil was extracted via three solvation methods: Soxhlet extraction, extraction via mixing and stirring, and lastly.super-critical fluid extraction. Major shale oil fractions were obtained from extract fractionation on chromatographic column. The nuclear magnetic resonance spectroscopy.technique was used to study.qualitatively.the fractional composition of OS extract. Results show that all studied OS deposits have quite similar trend in their particle size distribution and their elemental composition. These OS deposits are found to be vary.ng in their solvation behavior, fractional y.eld, and shale oil composition. Highest y.eld is obtained from polar solvents. The OS extraction via solvation processes is promising under certain extraction conditions such as super-critical conditions. The solvation variability.of Jordanian OS indicates that different extraction techniques suit different OS deposits. Such variability.should be considered in any.future extraction options.

Full knowledge of the phy.ical and mechanical behavior of limestone rocks is required for the safe design of structures. Little work has been done to characterize the phy.ical and mechanical properties of Jordanian limestone especially.under watery.environment. Therefore, in this study.the phy.ical and mechanical properties of some Jordanian limestone were investigated. The limestone samples were collected from five different parts of the country. The porosity.and dry.density.of the selected limestone were compared. The reduction on the compressive strength and tensile strength for dry. 50% and 100% water saturation were determined. All rock experienced a reduction on both the compressive strength and tensile strength as a function of saturation degree. Large reduction happens on the strength properties for the Zarka limestone than the other limestone when the samples are fully.saturated.
