Abstract

PROCESSO DE PREPARAçãO DE PRECURSOR MISTO MOLDADO PARA OBTENçãO DE CARBETO, NITRETO E SULFETO A presente invenção trata de um processo de preparo de materiais multimetálicos à base de metais de transição, empregando a coprecipitação de compostos mistos oriundos de soluções contendo os metais. A presente invenção trata de um processo de preparo de materiais multimetálicos à base de metais de transição, empregando a coprecipitação, preferencialmente buscando a condição de formação de um gel, a partir da mistura de soluções precursoras contendo os metais. Os parâmetros do processo são fixados de forma a resultar um material suscetível de conformação por extrusão, obtendo extrudados com propriedades fisico-quimicas superiores para serem utilizados como adsorvente, como catalisador ou suporte para catalisador, ou ainda, como enchimento de reator ou de coluna.
