<p>PURPOSE:To stably produce a high-performance treating agent for exhaust gas by mixing a sulfuric acid compd., halogen compd., and a material which can supply calcium oxide and is preliminarily mixed with water, and subjecting the mixture to noncohesive hydration treatment. CONSTITUTION:A material which can supply calcium oxide is mixed with water to prepare a dispersion liquid, into which one or more materials selected from those which can supply sulfuric acid compd., halogen compd., sulfides, alkali metal hydroxide, silicon dioxide, and aluminum oxide. Then the mixture is subjected to noncohesive hydration treatment to manufacture the treatment agent for exhaust gas. The noncohesive hydration treatment is performed by stirring or bubbling the mixture dispersion liquid in the range from room temp. to 180 deg.C so as to prevent generation of coarse grains due to coupling of particles.</p> |
