PROCESS FOR REGENERATING A MONOFUNCTIONAL LARGE-PORE ZEOLITE CATALYST HAVING HIGH SELECTIVITY FOR PARAFFIN DEHYDROCYCLIZATION

摘要

The present invention is a process for regenerating a large-pore zeolitic catalyst that has been deactivated by the formation of Group VIII metal agglomerates on the catalyst surface. In the process, the Group VIII metal agglomerates are redispersed to produce agglomerates of small size. It comprises an oxychlorination step, a nitrogen purge step and a reduction step.
