Abstract:
A process for the production of para-xylene is presented. The process includes the isomerization of C8 aromatics to para-xylene utilizing a new catalyst. The new catalyst and designated as UZM-54 is represented by the empirical composition in the as synthesized and anhydrous basis expressed by the empirical formula of: M m n+ R 1 r1 p 1 +  R 2 r2 p 2 +  Al 1-x E x Si y O z   where M is an alkali, alkaline earth, or rare earth metal such as sodium and/or potassium, R 1  and R 2  are organoammonium cation and E is a framework element such as gallium, iron, boron, or indium. UZM-54 are characterized by unique x-ray diffraction patterns, high meso surface area, low Si/Al ratios.
