ABSTRACT:
A process is described for rejuvenation of a deactivated highly siliceous noble metal-containing zeolite catalyst which contains agglomerated noble metals. The process comprises initially reducing the deactivated catalyst in hydrogen, pretreating the thus reduced catalyst with an inert gas stream containing about 0.001 to 10 weight percent hydrogen chloride, redispersing the noble metal with an inert gas stream containing about 0.001 to 10 weight percent Cl in the form of Cl.sub.2 or Cl-containing organic material, and subsequently reducing the catalyst. The Cl-treatments may optionally occur in the presence of oxygen or sources of oxygen.
