Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA FRENAR UNA POLIMERIZACION DE OLEFINA QUE SE REALIZA EN UN REACTOR DE FASE DE GAS A BAJA PRESION, ESTE PROCESO COMPRENDE LA INTRODUCCION DE UNA CANTIDAD EFECTIVA DE AGENTE DESACTIVADOR EN EL REACTOR, CARACTERIZADO EN QUE LA POLIMERIZACION DE OLEFINA SE REALIZA UTILIZANDO UN CATALIZADOR DE OXIDO DE CROMO Y EN QUE EL AGENTE DESACTIVADOR SE ELIGE ENTRE OXIGENO, AMONIACO, AGUA Y MONOXIDO DE CARBONO Y SE INTRODUCE DURANTE UN PERIODO DE TIEMPO RELATIVAMENTE CORTO. EL AGENTE DESACTIVADOR SE INTRODUCE PREFERIBLEMENTE EN EL REACTOR DE POLIMERIZACION EN UNA CANTIDAD TAL QUE EN EL REACTOR, LA PROPORCION DE PESO ENTRE EL AGENTE DESACTIVADOR Y EL CATALIZADOR ES COMO MINIMO 0, 001.
