Abstract

"PROCESSO E APARELHO PARA A PREPARAçãO E FORNECIMENTO DE PASTA DE CATALISADOR A UM REATOR DE POLIMERIZAçãO". Uma pasta de catalisador para um reator de polimerização (42) pode ser preparada em um tanque de mistura (14) e a pasta de catalisador alimentada a um ou mais tanques de armazenamento (18). Os tanques de armazenamento podem incluir agitadores (54), de modo que a pasta de catalisador é mantida em razão de sólido para líquido essencialmente homogênea. A partir do(s) tanque(s) de armazenamento, a pasta de catalisador pode ser bombeada (26) para o reator de polimerização (42), ao longo de uma passagem de fluido (34) possuindo um medidor de fluxo (38). o fluxo da pasta de catalisador pode ser contínuo e/ou ajustado com base em um parâmetro medido. A pasta de catalisador pode ser contínua e confiavelmente alimentada ao reator de polimerização (42).
