In this paper, oil shale samples from the Sultani deposit in the South of Jordan were pyrolysed in a semi-continuous fludized bed reactor under nitrogen and nitrogen/steam atmosphere. The pyrolysis temperature between 400 °C and 650 °C were investigated. Increasing the pyrolysis temperature from 400 °C to 520 °C caused a large increase in the oil yield. Further increase of the pyrolysis temperature resulted in a decrease in oil yield and a large increase in the evolved gases. This increase in the hydrocarbon gas yield was attributed to oil thermal cracking reactions. The evolved gases were composed of H₂, CO, CO₂, and hydrocarbons from C_l to C₄. The presence of steam improved the oil yield, which may be a result of reducing the degree of decomposition. The derived oils were fractionated into chemical classes using mini-column liquid chromatography.(5 figures, 3 tables, 37 references)
