✦ Synopsis

Oil shale samples from the Sultani deposit in the south of Jordan, were pyrolysed in a semi-continuous fluidized bed reactor under nitrogen and nitrogen/steam atmosphere. The pyrolysis temperature between 400 and 6508C were investigated. Increasing the pyrolysis temperature from 400 to 5208C 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 H 2 ; CO, CO 2 ; and hydrocarbons from C 1 to C 4 : 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.
