Abstract
Bituminous coals were desulfurized by leaching in a 325 ml, agitated, autoclave with hot, dilute solutions of carboxylic acids, buffered carboxylic acids, carboxylic salts, and carboxylic salt:alkali combinations. The partial pressure of oxygen was not increased as it was found not to increase the amount of organic sulfur removal. The effect of increasing carboxylic size and decree of desulfurization was studied. Among the carboxylic acids studied, formic acid removed the greatest amount of organic sulfur;and iso-valeric acid removed the greatest percentage of pyritic sulfur. It was found that there is a direct correlation between the amount of organic sulfur removal and the ASTM determined volatile matter of the coals.
