  • Process for regenerating a zeolite catalyst
    Patent number: 5138108
    Abstract: Disclosed is a process for regeneration of a 13X zeolite catalyst comprising conducting the following steps within the regeneration zone wherein the 13X zeolite is located.(1) Applying vacuum or delivering a source of molecular oxygen or inert gas at a temperature above 100.degree. C. to remove a portion of the volatile compounds from the 13X zeolite,(2) Cooling the 13X zeolite to a temperature below 100 degrees C.,(3) Contacting the 13X zeolite with an aqueous solution having a pH in the range of 7 to 14,(4) Drying the 13X zeolite,(5) Delivering an oxygen containing calcination gas to the regeneration zone and heating the 13X zeolite to a temperature in the range of 350.degree. to 450.degree. C.,(6) Cooling the 13X zeolite to a temperature below 100 degrees C., and(7) Contacting the 13X zeolite with an aqueous solution having a pH in the range of 7 to 14.
