The catalyst using ammonia as reducing agent, selective reduction decontamination nitric acid tail gas, nitrate tail gas, and due to the use of Nitric acid (nitrate) produces NOx,  NOx is converted to N₂and H₂O. Applicable to constant pressure, medium-pressure and double-pressurized nitric acid craft.
