Dolomitization in Campanian Oil Shale Rocks from South-Western Jordan

The Presence of Polycyclic Aromatic Hydrocarbons (pah) in Oil Obtained at Pyrolysis of Jordan Oil Shale

The presence of polycyclic aromatic hydrocarbons (PAH) in the oil obtained at pyrolysis of Jordan oil shale in a fluidised-bed reactor in the atmosphere of nitrogen and nitrogen/steam has been investigated. The final pyrolysis temperature was 520 °C, at which the maximum oil yield was established. The derived oils were fractionated into chemical classes using mini-column liquid chromatography f...

Value Added Products from Oil Shale

Oil shale is more than an energy source. It is also a source for various valuable materials. These materials include pyridine, carbonate minerals, alumina, ammonium sulfate, phosphate, sulfur, uranium, vanadium, and zinc, to name a few, from which numerous value-added products can be manufactured. For example, catalysts are made from vanadium and zinc, while alumina is a widely used material fo...

Vaporization Parameters of Primary Pyrolysis Oil from Kukersite Oil Shale

The objective of this study was to obtain vapor pressure and heat of vaporization values of the less volatile heavy end of the Kukersite oil shale primary pyrolysis oil and therefore to have a quantitative insight into the vaporization ability of the oil during the pyrolysis process. The shale oil was produced via rapid pyrolysis in a laboratory scale reactor and collected in a solvent filled c...

Radioactivity of surface soils from Oyo state, South Western Nigeria

Background: The activity concentrations of some radionuclides in soil samples collected from 20 locations in 8 major towns in Oyo State, Southwestern Nigeria have been determined by gamma-ray spectrometry technique. Materials and Methods: The activity concentrations were determined using high-purity germanium (HPGe) detector (Canberra Industries Inc.). The outdoor absorbed dose rates in air at ...
