Abstract

sistemas e métodos para dessulfatação de catalisadores incluídos em sistemas de póstratamento. a presente invenção se refere a um sistema de pós-tratamento para reduzir constituintes de um gás de escape que tem um teor de enxofre e compreende um catalisador de oxidação. um filtro é disposto a jusante do catalisador de oxidação. o sistema de pós-tratamento inclui também um controlador configurado para: em resposta à determinação de que o filtro deve ser regenerado e um critério de catalisador de oxidação ser satisfeito, aumentar uma temperatura do catalisador de oxidação para aumentar até uma primeira temperatura de regeneração que é maior que ou igual a 400 e menor que 550 graus celsius em resposta à determinação de que o filtro deve ser regenerado. o controlador faz com que o catalisador de oxidação seja mantido na primeira temperatura de regeneração durante um período predeterminado de tempo. o controlador é configurado para, subsequentemente, fazer com que a temperatura do catalisador de oxidação aumente até uma segunda temperatura de regeneração igual ou maior que 550 graus celsius.
