Abstract

<B>"ESTRUTURA DO TIPO COLMEIA PARA UM CATALISADOR"<D>. A presente invenção se refere a um catalisador compreendendo uma estrutura do tipo colmeia (1) e um invólucro envolvente, tal tipo de estrutura compreendendo uma estrutura formada de uma pilha de folhas metálicas, das quais pelo menos uma parte é feita de perfis, a estrutura do tipo colmeia incluindo diversos canais de fluxo livre para gás. Na estrutura do tipo colmeia, as extremidades livres das folhas metálicas são distribuídas sobre uma parte (S~ 1~) da sua periferia, de forma assimétrica ao centro da mesma, de modo que uma parte (F~ 1~) da periferia da estrutura, fica livre das extremidades livres das folhas metálicas. A dita estrutura do tipo colmeia é fixada diretamente ou através de uma camada intermediária ao dito invólucro, sobre uma área (L~ 1~) que compreende pelo menos parte das ditas extremidades livres.
