Abstract

"PROCESSO DE POLIMERIZAçãO DE OLEFINAS EM FASE GASOSA". A presente invenção compreende um processo de polimerização em fase gasosa compreendendo: (1) preparar uma solução de um precursor de catalisador compreendendo uma mistura de compostos de magnésio e titânio, um doador de elétron (s), e opcionalmente um solvente; (2) adicionar uma carga à solução da etapa (1) de maneira a formar uma pasta; 3) secar por aspersão a pasta da etapa (2) a uma temperatura de 100 a 140<198>C de maneira a formar um precursor secado por aspersão; (4) empastar o precursor secado por aspersão da etapa (3) em óleo mineral; (5) pré-ativar parcialmente ou plenamente o precursor de catalisador contatando a pasta de (4) com um ou mais ácido (s) de Lewis; e (6) transferir o precursor parcialmente ou plenamente ativado da etapa (5) para dentro de um reator de fase gasosa onde uma reação de polimerização de olefina esteja em desenvolvimento.
