摘要： A hydrocarbon feedstock is catalytically reformed to effect dehydrocyclization of paraffins in a process combination comprising a first reforming zone, a sulfur-removal zone containing a mixed reforming catalyst and sulfur sorbent comprising a manganese component to preclude sulfur from the feed to a second reforming zone. The process combination shows substantial benefits over prior art processes in achieving reforming-catalyst stability.

摘要： An improved dehydrocyclization process for the selective conversion of light hydrocarbons to aromatics is presented. The activity of a catalyst containing nonacidic L-zeolite is greatly enhanced by the addition of water, water precursors, or mixtures thereof to the reaction zone during the dehydrocyclization reaction. Addition of between 10 and 100 wt. ppm H.sub.2 O results in a higher product yield of aromatics with increased product octane.

摘要： A hydrocarbon solvent is utilized to purge contaminants, such as sulfur, from a conversion system. Complementary contaminant-removal steps may include oxidation, reduction, and contaminant removal with a sacrificial particulate bed. This solvent purge avoids deactivation of a subsequently loaded contaminant-sensitive catalyst, such as a reforming catalyst selective for dehydrocyclization.
