Abstract
An improved process for preparing a coal or lignite fuel that contains sulfur for combustion wherein reduced amounts of sulfur-containing air contaminants are emitted from the combustion. In a process whereby coal or lignite that contains sulfur is pulverized and subsequently mixed with a finely divided inorganic material, the improvement comprises precipitating the inorganic material onto the pulverized coal to achieve greater absorbency of SO.sub.2 emissions upon combustion of the coal. The inorganic material can be at least one of the oxide, hydroxide or carbonate of sodium, potassium, calcium or barium; or it can be dolomite.
