“…In addition, the calculated values of H are relatively low. Actually, they are in the range of energy required to disrupt secondary valence bridges (ca 2 to 20 kJ/mol), and a little bit approaching the lower values of the energy of hydrogen bonds (ca 20 to 40 kJ/mol) [28], with the exception of hexane and ethanol. This suggests a moderate temperature dependence of the dissolution process.…”

“…On the other hand, at higher temperatures (above 90 C) polar forces might lead to the interactions where solvents with high Hansen polar solubility parameters produced higher SOE. Furthermore, assuming that the shale/solvent system approached equilibrium, one may define a solution/extraction equilibrium constant, K, as [28]:…”

Oil shale as an alternative to oil is considered a major possible source of energy in Jordan which has an estimated 50 billion tons of geological proven reserves that are widely distributed all over the country. Many methods have been used for extracting shale oil from oil shale. This investigation suggests the application of a novel technique, namely microwaveassisted extraction. Several solvents were tested for extractive capacity at different temperatures (50 to 140 C) by the microwave irradiation of the investigated oil shale. The extraction results showed that all the solvents except hexane followed a sigmoid behaviour. Methanol exhibited the highest extractive capacity of about 23% of shale oil. Several particle sizes in the range of 94-910 m were examined and the results indicated that shale oil extraction is not diffusion controlled. The dynamic effect of extraction was also considered and found to have a very little effect after 10 minutes of irradiation.
