Abstract

"PRODUçãO DE POLIOLEFINA DE ALTO MODO DE CONDENSAçãO EM CONDIçõES TURBULENTAS EM UM LEITO FLUIDIZADO". Um processo de polimerização de olefina em leito fluidizado é operado no regime turbulento, embora utilizando mais de (17,5) porcento em líquido no fluido de recirculação para remover o calor da reação. A relação da densidade do leito fluidizado para a densidade do leito sedimentado, contrário às predileções da tecnologia anterior, pode ser mantida abaixo de (0,59).
