Development and Industrial Performance of a Zeolite-Based Xylene Isomerization Catalyst

摘要

The characteristics of catalysts based on the medium pore zeolite ZSM-5 and the wider pore zeolite Mordenite are compared and discussed in terms of reaction mechanisms and relative process economics. A bifunctional Mordenite-based catalyst has been developed and manufactured on a commercial scale. Data of industrial-scale application have demonstrated a high activity and selectivity for xylene and ethylbenzene isomerization in combination with an excellent stability.
