Abstract

"PROCESSO PARA PRODUZIR POLIETILENO COM CATALISADORES BASEADOS EM CROMO". Processo para polimerizar polietileno com catalisadores baseados em cromo, sendo que um ou mais catalisadores baseados em cromo suportados é misturado com óleo mineral para formar uma pasta e a pasta é então introduzida num reator de polimerização, especialmente num reator de polimerização em fase gasosa.
