METHOD OF CAPTURING SULFUR IN COAL DURING COMBUSTION OR GASIFICATION

摘要

ABSTRACTA method of reducing the amount of gaseous sulfur compoundsreleased during combustion of sulfur-containing fuel, comprisingthe steps of: (a) preparing a mixture of sulfur-containing particulate fuel and a sulfur absorbent, such as calcium oxide, cal-cium hydroxide, calcium carbonate, lime, limestone, dolomite, ormixtures thereof; (b) exposing the mixture to a reducing atoms-phere at a temperture of at least about 1500°F., so as to convertat least a portion of the particulate fuel into a gaseous portionand a solid, char portion; and (c) combusting the char portion,thereby forming an ash containing sulfur fixed therein.-19-
