Abstract

Un proceso unificado de destilación reactiva bajo presión para la alquilación de hidrocarburos aromáticos livianos, tales como el benceno y cumeno con olefinas C6 - C18 de cadena recta, utilizando un catalizador ácido sólido de alquilación colocado en la zona de reflujo de la columna de destilación. El proceso es continuo, utilizando una configuración de destilación reactiva en forma tal que por lo menos una parte de la olefina es inyectada por debajo de la zona de rectificación de benceno en el tope de la columna. El hidrocarburo aromático es inyectado en forma continua a baja velocidad por encima de la zona de rectificación en la base de la columna y por encima del rehervidor. La reacción de alquilación tiene lugar primordialmente en la fase líquida en el catalizador ácido sólido, y se caracteriza en que la relación molar del hidrocarburo aromático y la olefina en la fase líquida es ajustable. La relación molar es ajustable hasta alrededor de 100/l mediante un ajuste de la presión de operación de la columna interna, la tasa de reflujo del benceno, la cantidad de benceno removida del condensador de reflujo hasta el almacenamiento o desde el rehervidor, con la columna de destilación operada en o cerca de reflujo total del hidrocarburo aromático. Las inesperadamente altas relaciones molares entre el hidrocarburo aromático y la olefina en la fase líquida que se alcanzan en la columna de destilación reactiva aumentan la selectividad para aromáticos monoalquilatados, y ayudan a estabilizar la vida útil del catalizador.
