Removal of ammoniacal components from flue gas treated by selective non-catalytic reduction process, e.g. in waste incineration plants, involves contacting flue gas with ferro-oxide catalyst

摘要

Process for removing ammoniacal components from a flue gas treated by a selective non-catalytic reduction process involves contacting the flue gas with a ferro-oxide catalyst having a BET specific surface area of at least 0.2 m2/g at a temperature of at least 150 deg C.
