Abstract
La presente invencion se refiere a procedimiento para el control del balance térmico en la deshidrogenación catalítica de isobutano en un procedimiento catalítico de lecho fijo cíclico, adiabático, para la producción de isobutileno por la deshidrogenación catalítica de isobutano que contiene al meos 98 por ciento de isobutano en volumen separando el isobutileno del isobutano sin reaccionar y reclinando el material sin reaccionar al reactor catalítico, para generar calor dentro del reactor caalítico, caracterizado porque comprende los pasos de diluir la alimentación fresca con n-butano hasta una concentración de aproximadamente 3-7 por ciento en peso de la alimentacón; ajustar la concentración de n-butano en el rango de 3-7 por ciento para producir una alimentación de recirculación que tiene suficiente butadieno para producir coque adicional dentro de la zona de deshidrogenación y de ésta manera obtener un balance térmico neto aproximadamente de cero.
