Abstract

"PROCESSO PARA SINTETIZAR OU REGENERAR UM CATALIZADOR DE OXIDAçãO "ON-LINE" " Método "on-line"para sintetizar ou regenerar catalisadores para processos autotérmicos de oxidação, especificamente, a oxidação de hidrocarbonetos parafínicos, por exemplo, etano, propano e nafta, a olefinas, por exemplo, etileno e propileno. O catalisador compreende um metal do Grupo 8B, por exemplo, um metal do grupo de platina, e, opcionalmente, um promotor, tal como estanho, antimónio ou cobre, num suporte, preferivelmente um suporte monolítico. A síntese ou regeneração "on-line"envolve co-alimentar um composto de metal do Grupo 8B e/ou um composto promotor volátil com o hidrocarboneto parafínicos e oxigênio no reator de oxidação sob condições de ignição ou autotérmicas.
