| Zusammenfassung: | This invention presents a novel catalyst formulation for the isomerization of alkylaromatic hydrocarbons. The catalyst comprises at least one Group VIII metal, a pentasil zeolite wherein a portion of the aluminum atom has been replaced with gallium atoms and a matrix material of zirconia-alumina. When utilized in a process for isomerizing a non-equilibrium mixture of xylenes containing ethylbenzene, a greater yield of para-xylene is obtained compared to prior art processes. |
