  • Method of treating coal to remove sulfur and ash
    Patent number: 4305726
    Abstract: The present invention is directed to an improved method of chemically treating coal to remove sulfur and ash. It is especially adapted for use on high sulfur, refuse coal. In practice the coal is treated with hydrochloric acid and hypochlorous acid in the presence of ferric and ferrous sulfate to convert the iron pyrites to other sulfur compounds. These are then converted to various salts of calcium through neutralization with lime.
