Cold plasma reduction of sulphur dioxide to elemental sulphur. A. Czernichowski et al. Erdol Kohle Erdgas Petrochem., January 1995, 48(1), 30--32.

The aim of the study reported was to develop a simple, but efficient process for separating the sulphur oxides from flue gas streams by adsorption on activated carbon, their subsequent desorption with a reducing agent, and final reduction into elemental sulphur in a cold-plasma reactor. The results, which are presented and discussed, showed close to 70% SO2 conversion was obtained in a one-step laboratory scale experiment without use of any catalyst. 16 refs.
