Abstract

"PROCESSO PARA A POLIMERIZAçãO EM FASE GASOSA DEOLEFINAS". A presente invenção propicia um catalisadoraperfeiçoado à base de óxido de cromo suportado em um óxidorefratário granular ou microscópico para a polimerização de fasegasosa de pelo menos uma alfa-olefina que contém de 2 a 12átomos de carbono, em que o catalisador à base de óxido decromo suportado foi submetido a uma única etapa decalcinação/ativação que consiste em um único tratamento térmicorealizado a uma temperatura que varia de 200 a 450<198>C sobuma atmosfera que contém oxigênio.
