Abstract

"REATOR DE FASE GASOSA DE FLUXO RADIAL E MéTODO PARA REDUZIR O TEOR DE óXIDO DE NITROGêNIO DE UM GáS". Trata-se de um reator de fase gasosa de fluxo radial para redução catalítica seletiva de óxido de nitrogênio em uma corrente de gás inclui uma blindagem que encerra um espaço interior no qual fica localizada pelo menos um leito catalítico contendo um catalisador para conversão seletiva de NO~ x~. Um defletor direciona o fluxo de gás radialmente através do leito. Um injetor à montante do catalisador introduz um agente redutor, tal como amónia, na corrente do gás de entrada. O leito catalítico pode incluir catalisador particulado, monolítico ou produzido por microengenharia.
