Beschreibung
Zusammenfassung:	A non-equilibrium C8 aromatic-feed mixture is selectively isomerized to obtain an isomerized product enriched in para-xylene by contacting the feed in the presence of hydrogen with a catalyst containing a combination of a platinum group component with an SM-3 acidic crystalline silicaaluminophosphate molecular sieve at C8 aromatic isomerization conditions. The SM-3 molecular sieve is enriched in framework silicon at the surface, resulting in a greater yield of para-xylene compared to prior art processes.
