Myers, G A

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. (Official Gazette)
