Stable, high-yield reforming catalyst |
摘要 |
A reforming process, selective for the dehydrocyclization of paraffins to aromatics, is effected using a bed of catalyst particles containing multiple Group VIII (8-10) noble metals having different gradients within the catalyst particles and a nonacidic large-pore molecular sieve. The use of this bed of catalyst particles results in greater selectivity of conversion of paraffins to aromatics and improved catalyst stability, particularly in the presence of small amounts of sulfur.
