Abstract

Patente de Invenção: <B>MATERIAL DE CATALISADOR E UM PROCESSO PARA A PREPARAçãO DO MESMO".<D> A presente invenção proporciona um material de catalisador pulverulento à base de óxido de alumínio, que contém pelo menos um óxido metálico básico e pelo menos um metal nobre do grupo da platina do Sistema Periódico de Elementos além do óxido de alumínio. O material de catalisador é obtenível por carga de um material de suporte já estabilizado por óxidos básicos por impregnação renovada com mais óxidos básicos. Após secagem e calcinação desse material pós-impregnado em temperaturas abaixo de 800°C, os metais nobres cataliticamente ativos também são incorporados no material de suporte por impregnação.
