Abstract

CATALISADOR DE OXIDAÇÃO COM COLETOR DE FÓSFORO. A presente invenção refere-se a um catalisador, que * compreende um substrato de suporte com uma primeira extremidade a e uma segunda extremidade b, assim como do comprimento L, * uma zona de material A contendo um metal do grupo da platina em um material de suporte com uma quantidade de carga de 40 a 150 g/l, com base no volume do substrato de suporte e * zoma de material B contendo um metal do grupo da platina em um material de suporte com uma quantidade de carga de 75 a 200 g/l, com base no volume do substrato de suporte, sendo que a zona de material B apresenta uma teor maior de metal do grupo da platina, com base no volume do substrato de suporte e calculado em g/l do que a zona de material A e sendo que a zona de material B apresenta uma proporção de poros com um diâmetro de 0,5 a 50 µm de 20 a 30 %.
