Abstract
A liquid phase isomerization process comprising cofeeding molecular hydrogen at a feeding rate ≥100 ppm by weight can effectively convert a C8 aromatic hydrocarbon isomerization feed in the presence of an isomerization catalyst with a very low deactivation rate of the catalyst, even at high WHSV ≥5 hour−1.
