Patent ID: 7718842

Claim:
A process for separating meta-xylene from a hydrocarbon feed comprising isomers containing 8 carbon atoms, comprising: a step for bringing said feed into contact with a metaselective adsorbant comprising a faujasite type zeolite, the percentage of water in said zeolite being in the range 0 to 8% by weight and the adsorption temperature being from 25° C. to 250° C.; a desorption step employing a desorbant; and a step for separating meta-xylene from said desorbant; said process being characterized in that said desorbant is selected from the group consisting of tetraline methyl tetraline, ethyl tetraline, propyl tetraline, isopropyl tetraline, methylethyl tetraline, dimethyl tetraline and diethyl tetraline.
