Leachability of Oil Shale Ash from Isfir Al-Mahata Oil Shale, Southern Jordan

Suitability of Oil Shale Ash as a Constituent of Cement

Physical and chemical characteristics of ashes formed at burning oil shale at temperatures 500, 600, 700, 800, 900 and 1030 °C were studied. Standard procedures were used to determine both pozzolanic activity and binding parameters. The most suitable characteristics were provided with oil shale ash formed at 700 °C. Ashes (15 and 30%) were added to ordinary Portland cement. The optimum pozzolan...

Prospects in Waste Oil Shale Ash Sustainable Valorization

An innovative approach utilizing highly alkaline oil shale waste ash and carbon dioxide gas (CO2), associated with power production, as a resource for production of precipitated calcium carbonate (PCC) is introduced in this paper. The specifics and feasibility of the integrated ash valorization and CO2 sequestration process by indirect aqueous carbonation of lime-consisting ash were elaborated ...

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...

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...
