摘要：
The present invention relates to a solid formulation, more particularly to a pellet-type formulation that produces CO2 gas in a constant rate when contacting liquid acid. The pellet-type formulation of the invention is characterized in that the pellet is produced by the following: preparing a pellet by extrusion molding a composition that comprises a major amount of Sodium Carbonate (Na2CO3) and a minor amount of gelatin, and additionally a minor amount of synthetic resin that hardly reacts with acid; coating said pellet with a resin that hardly reacts with acid; and forming a recess or a hole at the center of the pellet. The present invention also relates to a process of preparing a pellet-type formulation that produces CO2 gas in a constant rate when contacting liquid acid.
