<p>Process for reduction of anionic components of chemicals, and compositions for use in the reduction process. Chemicals to be reduced are typically of the oxysulfur or sulfurnitrogen families. The reduction is carried out with mixing of carbonaceous fuel with the chemicals to be reduced. Reduction takes place in a reduction furnace having a char bed. Mixing in of the carbonaceous fuel may take place before introduction into the furnace, or may take place in the furnace itself. High levels, over 75%, of conversion are achieved in reducing sulfate to sulfide.</p> |
