ISOMERIZATION PROCESS WITH MTW CATALYST

摘要

An extruded C8 alkylaromatic isomerization catalyst is described. The catalyst has an average pore diameter in a range of about 110 Å to about 155 Å measured by BJH adsorption method and a pore volume less than about 0.62 cc/g measured by N2 porosimetry. A process for isomerizing a non-equilibrium C8 aromatic feed to provide an isomerized product is also described.

1. A process for isomerizing a non-equilibrium C8 aromatic feed to provide an isomerized product comprising:
contacting the non-equilibrium C8 aromatic feed with an extruded C8 alkylaromatic isomerization catalyst, comprising:
about 1 to about 20% by weight of an MTW zeolite;about 80 to about 99% by weight of a binder comprising an alumina;about 0.01 to about 2.00% by weight of a Group VIII metal calculated on an elemental basis;wherein the weight percents of the MTW zeolite, the binder, and the Group VIII metal, are based on a weight of the extruded catalyst, wherein the catalyst has an average pore diameter in a range of about 110 Å to about 155 Å measured by BJH adsorption method and a pore volume less than about 0.62 cc/g measured by N2 porosimetry.
