CPC classification number: C07C5/2737 , B01J29/7046 , B01J35/1014 , C07C4/18 , C07C2529/40 , C07C2529/70 , C07C15/08 , C07C15/04
Abstract: A process for the isomerization of a para-xylene depleted, meta-xylene rich stream under at least partially liquid phase conditions using ZSM-23 with an external surface area of at least 75 m2/g (indicating a small crystallite size), and a SiO2/Al2O3 ratio between 15 and 75 that produces a higher than equilibrium amount of para-xylene, i.e., more than about 24 wt % of para-xylene, based on the total amount of xylenes.
