Abstract

Method for the preparation of elemental sulfur, reducing sulfur dioxide, containing gases, by means of finely divided carbon at elevated temperature, characterized in that the finely divided carbon is introduced into a reaction chamber and suspended in sulfur dioxide containing gas introduced into the atmosphere. The same reaction chamber, the temperature of the suspension being maintained at about 1000 to 1800º c, the resulting reduced sulfide and sulfide containing gases being then treated by previously known methods, for the recovery of elemental sulfur.
