Detection of the incipient oxidation of coal by petrographic techniques

Author: Kruszewska, KJ ; Du Cann, VM Date: May 1996 Two petrographic methods, namely long-wave fluorescence intensity measurements and a vitrinite elasticity index were developed and used to detect incipient oxidation in coals subjected to simulated weathering conditions. The two methods are ... Read more
The nitric acid oxidation of coal. Part 4 Application of the graphical-statistical method to the interpretation of the investigations on the nitrohumic acids

Author: Van Duuren, BL Date: 1951 A graphical statistical method of representation of reaction mechanisms and products, developed by Van Krevelen has been used in the interpretation of the reactions of the nitrochumic acids from coal oxidation. Read more
Relating coal oxidation and hydrophobicity: a petrographic approach

Author: Kruszewska, KJ ; Labuschagne, BCJ ; Du Cann, VM Date: Nov 1996 Long-wave fluorescence relative intensity measurements and a vitrinite micro elasticity index were used to determine oxidation levels in a suite of artificially oxidized coals. These petrographic parameters were correlated with the agglomeration ... Read more
