Abstract

resumo dispositivo e processo para a eliminação de nox e de n2o a presente invenção se refere a um dispositivo e a um processo para a diminuição do teor de nox e de n2o em gases. o dispositivo compreende: a) um recipiente (1) e dispostas neste b) duas etapas de reação subsequentes para a eliminação de nox (etapa denox) por redução de nox com um agente de redução contendo nitrogênio, e, subsequentemente, para a eliminação de n2o por decomposição catalítica de n2o em n2 e em o2 (etapa den2o), as quais são constituídas por um ou por vários leitos de catalisador (7, 8) respectivamente e as quais são atravessadas pelo gás a purificar, em que c) pelo menos um leito de catalisador da etapa denox (7) contém um catalisador para a redução de nox com agentes de redução contendo nitrogênio, o qual contém zeólitos dopados com metais de transição, incluindo lantanídeos, d) pelo menos um leito de catalisador da etapa den2o (8) contém um catalisador para a decomposição de n2o em n2 e em o2, o qual contém um ou vários compostos catalíticos ativos de elementos selecionados dos grupos de 5 a 11 da tabela periódica dos elementos, excetuando os zeólitos dopados com ferro e e) antes da etapa denox (7) está previsto um dispositivo para a introdução do agente de redução contendo nitrogênio no fluxo de gás contendo o nox e o n2o. a combinação de catalisadores usada de acordo com a presente invenção permite uma estrutura muito simples e uma operação muito econômica do reator. 1/1
