摘要:
The present invention concerns a novel additive composition for reducing sulfur content of a catalytically cracked gasoline fraction. This additive composition comprises a support consisting of porous clay into which a first metal from group IV is incorporated and a second metal from group II is impregnated. Preferably, the first incorporated metal is zirconium and the second impregnated metal is zinc. The sulfur reduction additive is used in the form of a separate particle in combination with a conventional fluidized catalytic cracking catalyst in a fluid catalytic cracking process to convert hydrocarbon feed stocks into gasoline and other liquid products.

The invention relates to a four-component catalyst and a seven-component catalyst and refractory supports for use in the thermoneutral reforming of petroleum-based liquid hydrocarbon fuels.
摘要:
Compositions and processed for their use as additives for reducing the sulfur content of FCC gasoline employ a support material having deposited on its surface (a) a first metal component from Group IIB of the Periodic Table and (b) a second metal component from Group III or Group IV of the Periodic Table. The additive composition is preferably made of a montmorillonite clay support containing zinc and gallium, zinc and zirconium. Alternatively, the additive composition includes support material having deposited on its surface a metal component from Group III of the Periodic Table, preferably a montmorillonite clay support containing gallium. The clay is impregnated with the metal(s) using the known incipient wetness method and the dried powdered additive composition is preferably formed into shapes suitable for use in the FCC unit.

摘要:
The catalyst exhibiting hydrogen spillover effect relates to the composition of a catalyst exhibiting hydrogen spillover effect and to a process for preparing the catalyst. The catalyst has a reduced transition base metal of Group VIB or Group VIIIB, such as cobalt, nickel, molybdenum or tungsten, supported on a high porous carrier, such as saponite, the base metal being ion-exchanged with at least one precious metal of Group VIIIB. The process includes the steps of loading the base metal onto the support, reducing the base metal, preferably with H2 at 600° C., and thereafter ion-exchanging the precious metal with the base metal. Preferred examples of the catalyst include a saponite support loaded with about 10-20 wt % cobalt and about 0.1-1 wt % precious metal. The catalyst is optimized for reactions that occur in commercial processes at about 360-400° C., such as in hydrocracking.
