Effect of maceral properties on the comminution of coal. Technical progress report, January 1-March 31, 1986. [Resinite]
The objective is to study the chemical and physical properties of coal macerals and whole coal which are important in the comminution of coal. Swelling studies of pyridine extracted and o-methylated coals were made in various solvents. For the pyridine extracted coal swelling increased in cyclohexane, toluene, acetone and methanol. Swelling in tetrahydrofuran remained constant and decreased in pyridine. For the 0-methylated coal pyridine also-caused reduced swelling compared to the untreated coal. Tetrahydrofuran also caused reduced swelling while acetone, methanol and toluene caused enhanced swelling. Results of swelling are in agreement with the model preposed for coal swelling. Maceral separations of coal samples are being separated to provide sufficient sample for characterization studies on maceral fractions. Experiments have been initiated to study the grinding of coal in the presence of various solvents. 2 refs., 4 figs.
