POROUS QUICK LIME AND METHOD FOR PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide porous quick lime that has a low residual chlorine concentration and high collapsibility and a method of producing the same.SOLUTION: A porous quick lime has a chlorine concentration of less than 1000 ppm, and is composed of substantially spherical particles. A method for producing porous quick lime includes adding and firing an organic chlorine compound so that a chlorine component is 0.06-0.90 mass% relative to the mass of limestone.SELECTED DRAWING: Figure 1
【課題】残留塩素濃度が低く、かつ、崩壊性の高いポーラス生石灰およびその製造方法を提供する。【解決手段】本発明のポーラス生石灰は、塩素濃度が１０００ｐｐｍ未満で、かつ、略球状粒子から成ることを特徴とする。本発明のポーラス生石灰の製造方法は、石灰石の質量に対して塩素成分が０．０６〜０．９０質量％となるよう有機塩素化合物を添加して焼成することを特徴とする。【選択図】図１
