A new low temperature process for coal desulfurization
Abstract
Anumber of processes have been proposed to remove sulfur from coal. N-Chloro-P~tolucne sulfonamide sodium salt (Chloramine-T) and related compounds arc reported to have unique activity towards a wide range of organic sulfur compounds. The ability of these compounds to act as a source of i) halonium cations, ii) hypohalite species and iii) N-anions forms the basis of a new low temperature process for coal desulfurization.
Preliminary experimental results indicate that substantial organic sulfur reductions could be achieved by reacting high sulfur coals at low temperatures with aqueous chloramine-T solutions.
Keywords
