Abstract

Procedimiento para la preparación de isobuteno mediante disociación de MTBE, en el que se recorren las siguientes etapas: a) síntesis de MTBE; reacción de mezclas de hidrocarburos (II) con contenido en isobuteno con metanol (III), contenido en una o varias corrientes con contenido en metanol (VIII, IX), en intercambiadores de iones de carácter ácido, obteniéndose una corriente (IV) que contiene MTBE y TBA, b) separación de MTBE; separación destilativa de una corriente (V) que contiene MTBE y TBA a partir de la corriente (IV), c) disociación de MTBE; disociación de la corriente (V) en un catalizador heterogéneo en la fase gaseosa, obteniéndose una corriente (VI) que contiene al menos isobuteno, metanol, MTBE y agua, y eventualmente TBA, d) separación de isobuteno; separación destilativa de la corriente (VI), obteniéndose una corriente (VII) que contiene en cada caso más de 50% en masa de las cantidades de metanol, TBA y agua contenidos en la corriente (VI), y una corriente (XVII) que contiene isobuteno, e) separación del agua; separación destilativa de agua a partir de la corriente (VII) hasta una porción inferior a 1% en masa, obteniéndose una corriente (VIII), f) retorno; retorno completo o parcial de la corriente (VIII) con contenido en metanol a la síntesis de MTBE.
