ABSTRACT:
Zeolites washed with aqueous solutions or water or exhibit pH in the range of 9.4 to 10.0 and preferably 9.6 to 10.0 which can be converted to reforming catalysts with enhanced activity, selectivity and activity maintenance. Also processes for washing the zeolite to the target pH range and processes for using catalysts made with the washed zeolite to reform naphtha feeds.
