Abstract

Un método que comprende la calcinación de un precursor de catalizador que comprende cromo y un material de soporte de sílice a una temperatura en el rango de alrededor de 95?C a alrededor de 400?C en un lecho fluidizado por un gas que fluye a una velocidad de flujo volumétrico de alrededor de 2.5 a alrededor de 30 veces el volumen asentado del lecho por minuto para formar un precursor de catalizador calcinado. Un método que comprende la calcinación de un precursor de catalizador que comprende cromo y sílice a una temperatura en el rango de alrededor de 95°C a alrededor de 400°C con un gas que fluye a través del lecho a una velocidad espacial horaria de gas de alrededor de 15 a alrededor de 200 por hora. Un método que comprende la calcinación de un precursor de catalizador que comprende cromo y sílice a una temperatura en el rango de alrededor de 95°C a alrededor de 400°C con un gas que fluye a través del lecho a una velocidad espacial horaria en peso de alrededor de 1.9 a alrededor de 240 por hora.
