Abstract

Los compuestos aromáticos polinucleares (PNA) producidos como un subproducto en una zona de deshidrogenación de hidrocarburo se retiran y recuperan mezclando el fluente de la zona de deshidrogenación con una corriente de reciclado que contiene compuestos aromáticos mononucleares (MNA) y poniendo en contacto la mezcla resultante con un adsorbente para reducir la concentración de MNA y PNA y producir una corriente que comprende hidrocarburos deshidrogenados e hidrocarburos deshidrogenables. El absorbente gastado recuperado de la etapa de adsorción que contiene MNA y PNA se regenera poniéndolo en contacto un gas rico en hidrógeno para recuperar al menos una parte del MNA y PNA y por lo tanto regenerar el adsorbente gastado. El efluente que contiene hidrocarburo de la etapa de regeración después se separa en una corriente que contiene MNA y una corriente que contiene PNA y al menos una porción de la corriente que contiene NMA se recicla a la etapa de mezcla.
