Abstract

Converting both organic and inorganic sulfur compounds in coal to removable forms utilizing electron beam irradiation. The removable forms of sulfur include elemental suflur, gaseous compounds, and water-soluble compounds. Coal is pulverized and slurried and introduced into the electron beam reaction chamber where the conversion reactions take place. As a further benefit, coal dechlorination inherently results.
