ABSTRACT:
One exemplary embodiment can be an extruded C8 alkylaromatic isomerization catalyst. The extruded catalyst can include:about 2-about 20%, by weight, of an MTW zeolite;about 80-about 98%, by weight, of a binder including an alumina;about 0.01-about 2.00%, by weight, of a noble group metal calculated on an elemental basis; andabout 100 ppm-less than about 1000 ppm, by weight, of at least one alkali metal calculated on an elemental basis.Generally, the weight percents of the MTW zeolite, the binder, the noble group metal, and the at least one alkali metal are based on a weight of the extruded catalyst.
