<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment material excellent in the fixing capacity of an acidic gas such as chlorine gas, hydrogen chloride gas, sulfurous acid gas, a hyposulfurous acid gas and capable of fixing the acidic gas even in a high temperature region of about 1,000-1,300°C, a manufacturing method for a gas filter using the exhaust gas treatment material, and an exhaust gas treatment method. <P>SOLUTION: This exhaust gas treatment material contains a slag powder with a Braine specific surface area of 3,000 cm<SP>2</SP>/g or above of an electric furnace. The slag of the electric furnace discarded as industrial waste and not used effectively heretofore can be effectively utilized by using the exhaust gas treatment material. The exhaust gas treatment material is excellent in the fixing capacity of the acidic gas and the melting point of the exhaust gas treatment material in a state that the acidic gas is fixed on the exhaust gas treatment material is higher than that in a case using a conventional exhaust gas treatment material, and the acidic gas can be fixed up to the high temperature region of about 1,300°C by the exhaust gas treatment material. The exhaust gas treatment material is suitable for use in the gas filter for preventing the corrosion of incineration equipment and acidic rain and suppressing the production of dioxins. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
