To obtain a porous treating agent which effectively causes catalytic reaction with a harmful component and to provide a treating method with a high removing effect of the harmful component by using this treating agent.
An alkali substance powder containing a vaporizing component which separates and scatters by heating and which produces harmless salts by the reaction with a harmful component is added to the objective material to be heated such as waste. The mixture is heated to vaporize and scatter the vaporizing component as CO2 and H2O to form pores (a) and interconnecting pores (b) to increase the surface area. Then the harmful component is decomposed and precipitated from the objective material, and the harmful component such as HCl and Cl is ctalytically reacted to increase the reaction effect and to effectively produce a harmless chloride such as NaCl. Thus, the harmful component is removed.
