ABSTRACT:
A process for the dry carbonation of an ammonium or alkali metal carbonate containing material, or a mixture thereof, for conversion to the corresponding bicarbonate containing material comprising reacting in the solid phase an ammonium and/or alkali metal carbonate containing material with liquid water in a carbon dioxide rich atmosphere at a particle temperature of from about 125.degree. F. to about 240.degree. F. for a period of time sufficient to effect the desired conversion of the carbonate groups of said carbonate containing material to bicarbonate groups, the reaction temperature being controlled by the evaporation of liquid water at the reaction site and the removal of the resulting water vapor from the reactor atmosphere.
