Xylene Isomerization Catalysts for Ethylbenzene Dealkylation in Paraxylene Production
ISOXYL™ MPH Series
Edition Date :
February 06, 2026
ISOXYL™ MPH series catalysts provide highly efficient dealkylation of ethylbenzene for enhanced paraxylene (PX) production. By combining increased PX yields with reduced cost and energy consumption, the catalysts significantly improve plant economics and overall capacity. This makes ISOXYL MPH catalysts ideal for new units or for debottlenecking existing plants.
The ISOXYL MPH series is compatible with all state-of-the-art high-throughput applications, and used in GTC Technology’s GT-IsomPX process. Regardless of the process, ISOXYL MPH boasts maximum productivity at minimum loss of xylene and aromatics.
