More specifica - 0 tion, the field relates to liquid phase isomerization in complete absence of hydrogen which eliminates the need for gas-liquid separa- \" tion at the reactor outlet. Even in the absence of the hydrogen, the catalyst demonstrates a stable isomerization performance with a 0 paraxylene to xylene ratio of 23 wt% in the product stream.
