  • ACTIVATION OF OIL SHALE ASHES FOR SULFUR CAPTURE

    activation of ashes from oil shale combustion. For coal ashes, typically from fluidized bed combustion (FBC), limestone has been added as a source of calcium. In typical oil shales, there is a great deal of calcium carbonate present naturally. In an FBC boiler, there is enough time for sulfur adsorption, but with pulverized firing, that is not theGet Price
