Abstract

PROCESSOS PARA APERFEIçOAR UMA OU MAIS CARACTERìSTICAS DE DESEMPENHO DE UM OU MAIS CATALISADORES DE óXIDO METáLICO E PARA PRODUZIR áCIDOS CARBOX LICOS INSATURADOS São expostos catalisadores de óxido metálico modificados, que possuem diferentes propriedades químicas, físicas e catalíticas, quando usados para conversões catalíticas de compostos à base de carbono, quando comparados a catalisadores de óxido metálico não- modificados correspondentes. São descritos métodos para preparar os catalisadores modificados e sua utilidade no processo catalítico. Alquenos, ácidos carboxílicos saturados insaturados, ácidos carboxílicos saturados e seus análogos superiores são preparados diretamente a partir dos correspondentes alcanos, alquenos ou alcanos usando um ou mais catalisadores de óxido metálico modificados.
