    摘要: A reforming process, selective for the dehydrocyclization of paraffins to aromatics, is effected using a catalyst containing a uniformly distributed platinum-group metal component, a surface-layer metal component comprising one or more of the Group IVA metals, indium, Group VIIB (IUPAC 7) metals, iron, zinc, gold and bismuth and a nonacidic large-pore molecular sieve. The use of this bed of catalyst results in greater selectivity of conversion of paraffins to aromatics and in improved catalyst stability.

    摘要: Reforming selective for the dehydrocyclization of paraffins to aromatics, is effected using a catalyst containing a platinum-group metal, a nonacidic large-pore molecular sieve, and a metal modifier which is positioned on the catalyst to be extrinsic to the pores of the molecular sieve. The use of this catalyst results in greater selectivity converting paraffins to aromatics and improved catalyst stability particularly when processing feedstocks containing small amounts of sulfur compounds.

    摘要: A continuous process for upgrading reformate feedstock or the like to reduce benzene content and increase octane fuel rating. The improved process comprises maintaining a fluidized bed of regenerable acid solid medium pore zeolite catalyst particles in a turbulent regime reaction zone, preferably maintained with a superficial gas velocity of 0.1 to 1 meter/sec. with reformate feedstock being introduced at a bottom portion of the reaction zone at a weight hourly space velocity (WHSV) of 0.1 to 5, based on active catalyst solids; reaction zone total pressure being less than 2000 kPa. The preferred catalyst particles have an average particle size of 20 to 100 microns (.mu.), with about 10 to 25% of the catalyst particles comprising fine particles having a particle size less than 30 microns; and the preferred zeolite catalyst comprises shape selective medium pore aluminosilicate zeolite having a constraint index of 1 to 12. The benzene is reacted by contacting reformate feedstock, such as C.sub.6 distillation heart cut containing at least 70 wt % compounds having six carbon atoms, including benzene, n-hexane and isohexane, with said catalyst particles at reaction temperature of 370.degree. to 540.degree. C. and at benzene partial pressure of at least 200 kPa under reformate conversion conditions sufficient to convert at least 40% of feedstock benzene per pass, thereby producing a high octane fuel product containing less than 10 wt % C.sub.10.sup.+ components.

    摘要: Tin modified platinum-iridium catalysts provide high yields of C.sub.5 + liquid reformate in catalytic reforming, concurrent with high activity. In particular, the tin modified platinum-iridium catalysts are of unusually high selectivity, as contrasted with known iridium promoted platinum catalysts. The high selectivity is manifested in reforming a naphtha feed in a reactor charged to capacity with the catalyst, but particularly when used in the dehydrocyclization zone, or tail reactor of a series of reactors, while the lead reactors of the series contain a non tin-containing platinum catalyst, especially a platinum-iridium, or a platinum-rhenium catalyst. The tin modified platinum-iridium catalysts are also highly active, with only moderate loss in the high activity for which iridium stabilized platinum catalysts are known.
