Abstract
Procedimiento para la desproporcionación
selectiva de
compuestos aromáticos con conversión incrementada.
compuestos aromáticos con conversión incrementada.
Se describe un proceso mejorado para la
desproporcionación selectiva de tolueno. El proceso usa
preferiblemente un catalizador de desproporcionación que comprende
una zeolita de tipo pentasil tal como MFI que está enlazada con
fosfato de aluminio. Llevar a cabo el proceso a una conversión de
tolueno mayor que 30% en peso y a una razón de hidrógeno a
hidrocarburo menor que 3,0, y especialmente una razón de 0,1 a 1,0,
mejora el máximo rendimiento de paraxileno. El rejuvenecimiento
periódico aumentando la razón de hidrógeno a hidrocarburo elimina
algunos depósitos de carbono y restablece la actividad catalítica.
Un gas diluyente inerte ayuda en la
pre-coquificación selectiva del catalizador
también.
