Abstract
A reforming process, selective for the dehydrocyclization of paraffins to aromatics, is effected using a large-pore molecular-sieve catalyst containing a uniformly distributed platinum-group metal component, and a tin component incorporated into the large-pore molecular sieve by secondary synthesis. The use of this catalyst results in greater selectivity of conversion of paraffins to aromatics and in improved catalyst stability.
