Abstract
"PROCESSO PARA DESENCADEAMENTO DE POLIMERIZAçãO DE OLEFINA". A presente invenção se refere a um processo para desencadear uma reação de polimerização de olefina numa fase gasosa posta em execução usando um catalizador baseado em óxido de cromo em um reator de leito fluidificado, através do qual passam reações de misturas de gases contendo a olefina caracterizada pelo fato de que o desencadeamento da reação de olefina é introduzida no reator até que a produção desejada de polímero seja estendida por meios de processos de 2 estágios, durante o primeiro estágio no qual a introdução de olefina é posta em execução para fim de manter constante a pressão parcial de olefina no reator e durante o segundo estágio, a introdução de olefina é regulada a taxas constantes de fluxo.
