Abstract

a presente invenção refere-se a processo para produção de composição de polietileno multimodal no sistema de reatores, compreendendo: polimerizar etileno num meio de hidrocarboneto inerte no primeiro reator na presença de sistema catalisador, e hidrogênio em 0,1-95% em mol em relação ao gás total presente na fase vapor no primeiro reator, para obter polietileno de baixo peso molecular ou polietileno de peso molecular médio; remover na unidade de remoção de hidrogênio 98,0 a 99,8% em peso do hidrogênio compreendido numa mistura obtida do primeiro reator sob uma pressão de 103-145 kpa (abs) e transferir a mistura para o segundo reator; polimerizar etileno e opcionalmente comonômero de a-olefina de c4 a c12 no segundo reator na presença de sistema catalisador, e na presença de hidrogênio numa quantidade obtida na etapa (b), para obter primeiro polietileno de alto peso molecular ou primeiro polietileno de peso molecular ultraelevado sob a forma de homopolímero ou copolímero e transferir a mistura para o terceiro reator; e polimerizar etileno e opcionalmente comonômero de a-olefina no terceiro reator na presença de sistema catalisador, e hidrogênio, em que a quantidade de hidrogênio no terceiro reator é de 0,1-70%, em relação ao gás total presente na fase vapor no terceiro reator ou opcionalmente ausência de hidrogênio, para obter segundo polietileno de alto peso molecular ou segundo homopolímero ou copolímero de polietileno de peso molecular ultraelevado; e composição de polietileno multimodal.
