Abstract

UN PROCESO PARA LA RECUPERACION DE UN CATALIZADOR DE ACIDO SULFONICO DE UN EXTRACTO ACUOSO DE UN CHORRO EFLUENTE DE ALQUILACION QUE CONSISTE EN LOS PASOS SIGUIENTES: EVAPORAR EL EXTRACTO PARA OBTENER UN HIDRATO DEL CATALIZADOR DE ACIDO SULFONICO; HACER REACCIONAR EL HIDRATO CON UN CHORRO HIDROCARBURO QUE CONTENGA OLEFINAS PARA OBTENER SU ESTER DE ACIDO SULFONICO; E INTRODUCIR EL ESTER DE ACIDO EN UN SISTEMA DONDE TENGA LUGAR UN PROCESO DE ALQUILACION DE UN MATERIAL HIDROCARBURO CON UN AGENTE DE ALQUILACION OLEFINICO BAJO CONDICIONES DE ALQUILACION, CON LO QUE EL ESTER DE ACIDO SULFONICO SE DESCOMPONE A SU FORMA ACIDA QUE ES CATALITICAMENTE ACTIVA EN EL PROCESO DE ALQUILACION.
