Abstract

"REATOR DE FASE GASOSA E PROCESSO PARA REDUZIR óXIDO DE NITROGêNIO EM UMA CORRENTE DE GáS". Trata-se de um reator de fase gasosa para a redução catalítica seletiva de óxido de nitrogênio em uma corrente de gás que inclui um invólucro encerrando um espaço interior no qual está localizado pelo menos um leito de catalisador contendo um catalisador para a conversão seletiva de NO~ x~. Um injetor a montante do catalisador introduz um redutor tal como amónia na corrente de gás de entrada. O leito de catalisador pode incluir material particulado, monólito, ou catalisador microprojetado. Um queimador é empregado para elevar a temperatura da corrente de gás de entrada. Um permutador de calor é usado para transferir calor a partir do gás tratado para o gás de entrada, opcionalmente um defletor é usado para defletir o fluxo de gás através do permutador de calor.
