Abstract
Xylene isomerization is carried out using specific non-zeolitic molecular sieve catalyst, e.g., the silicoaluminophosphate molecular sieves of U.S. Pat. No. 4,440,871, to provide improved production of p-xylene from C.sub.8 aromatic compounds and the conversion of ethylbenzene to a xylene.
