Abstract

"PROCESSO PARA PREPARAR POLIETILENO A PARTIR DE ETILENO DE ALIMENTAçãO". Um processo para o preparo de polietileno a partir de "etileno de alimentação" compreende: a) um estágio de hidrogenação em que o "etileno de alimentação" que contém impurezas ou componentes secundários tais como acetileno e etano é reagido com hidrogênio para remover o acetileno através de hidrogenação catalítica para formar etileno e parte do etileno é convertida em etano, e b) um estágio de polimerização em que o etileno que deixa o estágio a) é reagido na fase gasosa em um reator de leito fluidizado para formar polietileno, em que o gás fluidificante usado consiste de, ao entrar no reator, eteno e de 20 a 70% em volume de etano, baseado no volume total do gás fluidificante, possivelmente em conjunto com componentes adicionais, em que, em a), o etileno é convertido em uma maneira almejada em etano além do etano já presente no "etileno de alimentação" de modo que a concentração especificada em b) resulta. Um aparelho para realização do processo é também proporcionado. No processo reivindicado, o etano é usado para aumentar a capacidade térmica do gás fluidificante usado.
