Abstract :
The aim of this work is study aimed to investigate the effect of the mineral matrix on supercritical water extraction of Moroccan oil shale (Timahdit area), to establish the best operating conditions likely to give a good yield of recovery (26.16%) with the best oil quality. The yield of the oil produced depends on the type of material used to extract the organic matter of oil shale: crude oil shale, oil shale decarbonized and the solvent (water, limewater, toluene and olive oil mill wastewater). Several results show that the mineral matrix and the olive oil mill wastewater has a significant effect on of the supercritical water extraction yield of shale oil, giving a better quality of the extracted oil. It is still another object to provide an efficient solvent extraction process for the recovery of oil shale wherein not toxic and law cost solvent can be employed and good percentages of oil shale can be recovered in a relatively inexpensive and easy. The FT-IR spectra show that, the extracted oil containing a substantial proportion of aromatic hydrocarbon compounds and fewer amounts of paraffins.
