    摘要： A process is provided for loading and uniformly distributing platinum onto a Zeolite-L. The Zeolite-L is contacted with an aqueous solution containing a platinum salt and a non-platinum metal salt, wherein the non-platinum metal salt is present in solution in an amount which is critical to preventing the formation of acid sites as well as avoiding an excess of metal ions in the form of a salt which could block the pores of the Zeolite-L. The Zeolite-L is then aged to allow the platinum to migrate and uniformly distribute throughout the Zeolite.

    摘要： A class of catalysts which exhibit superior activity maintenance in dehydrocyclization reactions are defined as a type L zeolite having exchangeable cations of which at least 75% are selected from Group IA and calcium and barium cations and containing well dispersed particles of at least one Group VIII noble metal where more than 90% of the noble metal thereof is dispersed in the form of particles having a diameter less than 7 A. The catalysts may also be identified as type L zeolites loaded with at least one Group VIII noble metal which have a terminal cracking index (as a measure of production of pentanes versus butanes from hexane) of at least 1.5.
