Zeolite catalyst and process for using said catalyst.
摘要
<p>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 ANGSTROM . 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.</p>
