Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO DE UM CATALISADOR"<D>. A invenção refere-se a um processo para preparação de um catalisador que tem um revestimento cataliticamente ativo consistindo de materiais finamente divididos e de elevada área superficial e componentes cataliticamente ativos sobre uma estrutura de suporte inerte. Uma mistura em pó dos materiais finamente divididos usados é impregnada com uma solução de compostos precursores dos componentes cataliticamente ativos. Por combinação adequada dos materiais finamente divididos e dos compostos precursores e controle apropriado do processo de impregnação, uma deposição altamente dispersa e adsorção dos componentes cataliticamente ativos é assegurada sobre os materiais finamente divididos. Em seguida, uma dispersão de revestimento aquosa é produzida usando-se a mistura em pó impregnada e a estrutura de suporte é revestida com a mesma. O revestimento é então seco e calcinado.
