“…According to Haddadin [22], the samples of El-Lajjun oil shale undergo softening and molecular rearrangement up to 330 °C. Thereafter, heating up to 500 °C results in evolution of oil and gas corresponding to the weight loss by 23% in the untreated shale and by 42% in the decarbonated shale.…”

A short overview of the previous works concerning oil extraction from Jordanian oil shale is presented. The results of the systematic experimental study obtained in this work on the effects of temperature (320-420 °C) and exposure time (0-10 h) at nominal temperature on the yield of pyrolysis products from Attarat oil shale generated in autoclaves without any solvent and in the presence of benzene, water and tetralin are described. The yields of solid residue, gas, pyrolytic water and subsequent extracts with benzene (thermobitumen and oil (TBO) including asphaltenes and hexane solubles) and tetrahydrofurane (asphaltols) were estimated. The compound groups of TBO were assessed. The highest yield of TBO, 59.4% of organic matter (OM), was obtained at a temperature of 420 °C and duration 0.25 h. The 20% lower yield of TBO from Jordanian oil shale OM in comparison with that from Estonian Kukersite OM is explained by close values of the apparent kinetic constants estimated for the overall decomposition of the Attarat oil shale OM, and for the secondary decomposition of TBO.

“…Thermal behavior of Jordan oil shale has been studied by Haddadin et al [14,15] on the basis of isothermal and non-isothermal weight loss using TGA, and by Kraisha [16] under rapid heating conditions in a flash pyrolysis unit. The TGA curves exhibited two endothermic peaks: s.c. softening (molecular rearrangements) and volatilization whose rate characteristics were found from the relationship…”

An approximate step-by-step model has been deduced for description of the thermal decomposition kinetics of Estonian oil shale in an autoclave under non-linear increase of temperature. The apparent first-order kinetic constants have been estimated for the overall parallel formation of gaseous and liquid phases from the initial organic matter, for the parallel and consequent formation of gas from the liquid product at the stage of oil shale thermal decomposition, and for the parallel formation of gas and solid residue from the liquid product in the cracking stage. A linear dependence between the apparent Arrhenius constants lnA = 0.179E -3.258 (n = 24, r = 0.991) was revealed for different kinetic steps of kukersite pyrolysis using the constants estimated in this work and published by others.
