Liquid phase xylene isomerization in the absence of hydrogen

摘要

The field of this claimed subject matter generally relates to liquid phase isomerization technology. More specification, the field relates to liquid phase isomerization in complete absence of hydrogen which eliminates the need for gas-liquid separation at the reactor outlet. Even in the absence of the hydrogen, the catalyst demonstrates a stable isomerization performance with a paraxylene to xylene ratio of about 23 wt % in the product stream.
