Abstract

MÉTODO PARA REGENERAR UM CATALISADOR DE TRATAMENTO DE GÁS DE ESCAPAMENTO, E, CATALISADOR DE TRATAMENTO DE GÁS DE ESCAPAMENTO. Um método para regenerar um catalisador para a descarga de gás de tratamento (11) que têm cinzas aderentes à sua superfície. O método compreende: uma etapa de trituração (Sl) em que o catalisador para a descarga de gás de tratamento (11) é triturado de modo que de 70 a 95 % em peso do catalisador total para a descarga de gás de tratamento (11) torne-se pedaços grossos (12) tendo um tamanho que excede um tamanho inicial (S) (qualquer valor desejado na faixa de 0,105 a 1,0 mm) ; uma etapa de separação (S2) em queas partículas obtidas pela trituração do catalisador para a descarga de gás de tratamento (II) são separadas em pedaços grandes (12) tendo um tamanho que excede o tamanhoinicial (S) e um pó fino (13) tendo um tamanho não maior do que o tamanho inicial (S) ; uma etapa de pulverização (S3) em que os pedaços grossos (12) separados são pulverizados em partículas finas tendo um diâmetro de partícula médio de 0,1] mm ou menor; umaetapa de amassamento (S4) e etapa de moldagem (S5) em que as partículas finas são amassadas juntas com outros materiais e a mistura é moldada em um catalisador para a descarga de gás de tratamento e uma etapa de secagem (S6) e etapa de queima (S7) em que a forma bruta moldada é secada e queimada para obter um catalisador regenerado para a descarga de gás de tratamento (14).
