Abstract
One exemplary embodiment can be a molecular sieve for a catalyst for isomerizing xylenes. Generally, the molecular sieve, including at least one of an MFI, MEL, FER, MOR, TON, MTW, EUO, and MTT zeolite, can include: at least about 40%, by weight, silicon; about 0.5-about 7.0%, by weight, gallium; and about 0.1-about 2.0%, by weight, of another IUPAC Group 13 element wherein the silicon, gallium and the another IUPAC Group 13 element are calculated on an elemental basis.
