ABSTRACT:
A process is described for regenerating a coke and poison deactivated noble metal-containing zeolite catalyst material. The activity of the catalyst after oxygen regeneration can be improved by treating the oxidized catalyst at temperatures from 100.degree. to 250.degree. C. (212.degree.-482.degree. F.) or lower, preferably 100.degree. to 200.degree. C. (212.degree.-392.degree. F.), or most preferably 150.degree. to 200.degree. C. (302.degree.-392.degree. F.), in a reducing atmosphere, as opposed to higher conventional reducing temperatures. The process permits catalyst reactivation by removing coke and other poisons, such as nitrogen, from the catalyst while avoiding excess agglomeration of the noble metals thereon.
