Carbon dioxide/water for coal benefication
Conference
·
OSTI ID:5069427
Pressurized carbon dioxide/water solvents affect the chemical and physical properties of coal to provide a method of simultaneous cleaning and fracturing. The synergistic interaction of these two inexpensive reagents causes the selective solubilization of the alkali and alkaline earth mineral matter in the coal and the swelling of the coal matrix which weakens the coal structure. Significant improvements in coal grindability with high retention of energy content have been achieved. 11 refs., 3 figs., 7 tabs.
