STAGED COMBUSTION PROCESS AND SYSTEM FOR REGENERATING A REFORMING OR AROMATICS PRODUCTION CATALYST IN A MOVING BED

摘要

the invention relates to a moving bed regeneration process of a catalyst for production of aromatic hydrocarbons, hydrogen and the catalyst containing a support,at least one noble metal and at least one halogen, process of the combustion stage with treatment of the catalyst in at least two successive combustion zones.a process in which, each combustion zone is separated from the adjacent combustion zones so as to allow the catalyst and prevent the passage of gas.in each zone is introduced in a gas containing oxygen and the gas products are extracted from each zone.the severity of the operating conditions in each zone increases with the direction of flow of the catalyst.advantageously, the combustion stage is in a control zone of end of combustion is characterized by little or no consumption of oxygen.the invention also relates to the device for implementing the process.
