METHOD FOR REMOVING ARSENIC COMPOUND, METHOD FOR REGENERATING NOX REMOVAL CATALYST, AND NOX REMOVAL CATALYST |
摘要 |
Provided is a practical method for dry-separating arsenic compounds from a used NOx removal catalyst contaminated with arsenic. The method for removing arsenic compounds comprises heat-treating a NOx removal catalyst contaminated with arsenic compounds at a predetermined temperature in a reducing atmosphere while exposing the catalyst to hydrocarbon compounds (except CH4) or oxygen-containing carbon compound. |
