ABSTRACT:
One exemplary embodiment can be an ion-exchanged xylene isomerization catalyst. The ion-exchanged xylene isomerization catalyst can include:about 1-about 99%, by weight, of at least one of MFI, MEL, EUO, FER, MFS, MTT, MTW, TON, MOR, and FAU zeolite;about 1-about 99%, by weight, of a binder having an aluminum phosphate; andno more than about 350 ppm, by weight, of a noble metal based on the weight of the catalyst. Generally, the catalyst has a quotient of (CO area)/(weight % of the noble metal) of no more than about 0.10.
