Abstract

Patente de Invenção: <B>"CATALISADORES à BASE DE OXICARBONETO DE MOLIBDêNIO MODIFICADO PREPARADO A PARTIR DE óXIDO DE MOLIBDêNIO ORIENTADO E SEU PROCESSO DE OBTENçãO"<D>. Catalisador à base de oxicarboneto de molibdênio modificado que tem uma superfície específica superior a 5 m^ 2^/g e uma atividade catalítica melhorada, em especial a velocidade específica, caracterizado pelo fato de que ele é preparado a partir de um óxido de molibdênio MoO~ 3~ que tem uma estrutura que possui essencialmente plaquetas monocristalinas orientadas em uma direção preferencial obtidas por sublimação-condensação, e seu processo de obtenção.
