Abstract

"PROCESSO PARA A OXIDAçãO DIRETA DE OLEFINAS A óXIDOS DE OLEFINAS". A presente invenção compreende um processo para a oxidação direta de uma olefina, tal como propileno, por oxigênio ao correspondente óxido de olefina, tal como óxido de propileno. O processo envolve contatar a olefina com oxigênio sob condições de reação na presença de um agente redutor, tal como hidrogênio, e na presença de um catalisador. O catalisador compreende um componente metálico, tal como um óxido de metal de transição, disperso sobre um metalossilicato sibmetido a troca iónica metálica, tal como um aluminossilicato poroso submetido a troca com íons do Gtupo 1 ou do Grupo 2. A seletividade a óxido de olefina é alto, e o catalisador é prontamente regenerado.
