✦ Synopsis
Edited by Gavasci er rrl.
From eight deposits in central Mongolia, oil shale samples were removed and pyrolysis experiments were conducted on them. The best quality oil shale gave 15% pitch. The process of distillation allowed liquid fractions and solid residues to be obtained. After acids, organic bases and phenolic compounds have been isolated from each fraction, these liquid products can be used as diesel, oil materials, binding materials (bitumen-like hard residue) and gasoline.

Application of computer modelling to predict the leaching behaviour of heavy metals from MSWI fly ash and comparison with a sequential extraction method Herck, P. V. Wasre Munoge., 2000, 20, (2/3), 203-210. Combustion residues in general and MSWI fly ashes in particular form a major environmental problem as they are polluted with heavy metals. The heavy metals can be removed from the fly ash by leaching with for example the acid wastewater obtained in the wet scrubber of the air pollution control system. The remaining fly ash can be land-filled or valorized.
