摘要： A unified process for reactive distillation under pressure for the alkylation of light aromatic hydrocarbons such as benzene and cumene with straight chain C6-C18 olefins using a solid acid alkylation catalyst supported in the reflux zone of the distillation column. The process is continuous, using a reactive distillation configuration such that at least a portion of the olefin is injected below the benzene rectification zone at the top of the column. The aromatic hydrocarbon is injected continuously at a low rate above the rectification zone at the base of the column and above the reboiler. The alkylation reaction takes place primarily in the liquid phase on the solid acid catalyst and is characterized in that the molar ratio of aromatic hydrocarbon to olefin in the liquid phase may be adjusted. The molar ratio is adjustable up to about 100/1, through adjustment of the internal column operating pressure, the benzene reflux rate, the amount of benzene removed from the reflux condenser to storage or from the reboiler with the distillation column operated at or near total aromatic hydrocarbon reflux. The unexpectedly high liquid phase aromatic hydrocarbon to olefin molar ratios achieved in the reactive distillation column increases the selectivity to mono-alkylated aromatics and helps stabilize catalyst lifetime.

摘要： Un proceso unificado que combina un proceso unico de regeneracion del catalizador en el sitio con una destilacion reactiva continua bajo presion para la alquilacion de hidrocarburos aromaticos livianos, tales como benceno con olefinas C2-C30, usando un catalizador de acido solido para alquilacion sostenido en la zona de reflujo (21) de una columna de destilacion (Seccion A). La regeneracion periodica del catalizador (Secciones E, F y G) se lleva a cabo con una inyeccion contracorriente de una parafina C4-C16 (35) por debajo de la zona de rectificacion de benceno en la parte superior de la columna, pero por encima de la zona del catalizador, mientras se inyecta la carga de hidrocarburo aromatico para reaccion (17) de manera continua en un punto por encima de una zona de rectificacion en la base de la columna donde el compuesto aromatico es separado de la parafina y los subproductos son lavados para retirarlos del catalizador. El uso de parafina C4-C16 con el hidrocarburo aromatico en un porcentaje molar en el rango de 40 a 90% permite una temperatura de regeneracion de alrededor de 175-250 degree C, que se logra y se mantiene regulando la presion de la columna y la tasa de reflujo del hidrocarburo aromatico. Se necesitan presiones significativamente mas bajas, del orden de 125 a 370 psig, para lograr la temperatura de regeneracion que las que se requeririan con el uso solamente del hidrocarburo aromatico para diluir y lavar los subproductos de las superficies del catalizador.
