Abstract
Reivindicación 1: Un proceso para producir a-olefinas que comprende poner en contacto una alimentación de etileno con un sistema de catalizador de oligomerización en una zona de reacción de oligomerización en condiciones de reacción de oligomerización para producir una corriente de producto que comprende a-olefinas en donde el sistema de catalizador comprende un complejo de hierro ligando y un cocatalizador de metil aluminoxano modificado (MMAO) en donde la corriente de alimentación de cocatalizador a la zona de reacción se diluye en un solvente hasta una concentración de menos de 1% en peso de aluminio en la corriente de alimentación de cocatalizador. Reivindicación 7: Un proceso para producir a-olefinas que comprende: a. preparar una corriente de cocatalizador al diluir, en una primera etapa de dilución, una corriente de metil aluminoxano modificado (MMAO) que tiene una concentración de más de 4% en peso de aluminio en un primer solvente para formar una corriente de cocatalizador con una concentración de menos de 1,5% en peso de aluminio; y b. poner en contacto una alimentación de etileno con un sistema de catalizador de oligomerización en una zona de reacción de oligomerización en condiciones de reacción de oligomerización para producir una corriente de producto que comprende a-olefinas en donde el sistema de catalizador comprende un complejo de hierro ligando y la corriente de cocatalizador.
