Abstract

PROCESSO PARA A REMOÇÃO DE NOx E ÓXIDO DE DINITROGÊNIO NO EFLUENTE GASOSO DO PROCESSO. Processo para remoção de NOx (NO, NO2) e óxido nitroso (N2O) contidos em um efluente gasoso compreendendo as etapas de (a) adicionar uma quantidade de um agente redutor de NOx no efluente gasoso do processo; (b) em primeiro estágio passar o efluente gasoso misturado com o agente redutor através de um catalisador ativo na redução catalítica seletiva de NOx com o agente redutor e proporcionar um efluente gasoso compreendendo o óxido nitroso e quantidades residuais do agente redutor; e (c) em um segundo estágio, passar o efluente gasoso através de um catalisador compreendendo um composto de cobalto e sendo ativo na decomposição de óxido nitroso e oxidação das quantidades residuais do agente redutor.
