BIMETALLIC Pt-Ni CATALYSTS SUPPORTED ON USY ZEOLITE FOR n-HEXANE ISOMERIZATION
Isomerization of linear alkanes has had considerable importance for the refining industry because the isomers formed in this reaction have high octane number. Most works reported in the literature studied the use of bifunctional catalysts, i.e., ones that have acid sites and metallic sites. In this study, bifunctional monometallic (Ni or Pt) and bimetallic catalysts (Pt-Ni), using HUSY zeolite ...
متن کاملLow-temperature SCR of NO with NH3 over noble metal promoted Fe-ZSM-5 catalysts
We have reported previously the excellent performance of Fe-exchanged ZSM-5 for selective catalytic reduction (SCR) of NO with ammonia at high temperatures (300–400 C). In this work, we found that the reaction temperature could be decreased to 200– 300 C when a small amount of noble metal (Pt, Rh, or Pd) was added to the Fe-ZSM-5. The SCR activity follows the order Pt/FeZSM-5 > Rh/Fe-ZSM-5 > Pd...
متن کاملCatalytic decomposition of CF4 over copper promoted mesoporous catalysts
A series of mesoporous catalysts (MCM-41) promoted by copper oxide nanoparticles were prepared by the co-precipitation method and tested for the decomposition of carbon tetrafluoride (CF4). The addition of copper oxide nanoparticles to MCM-41 led to an improvement in the catalytic activity for CF4 decomposition. The catalyst was the most active around 5 wt% copper oxide added to MCM-41. Methods...
متن کاملWater-gas Shift Reaction over Ceria-promoted Pt catalysts
Introduction The fuel processor in which hydrocarbon fuels can be converted into hydrogen has recently attracted much attention as a result of the advancement in the fuel cell technology. In a fuel processor, the water-gas shift (WGS) reaction plays a crucial role in the transformation of CO, a well-known poisonous gas to electrode of fuel cell, into hydrogen through reaction with steam. In WGS...
متن کاملHydrogenation of carbon monoxide over vanadium oxide- promoted rhodium catalysts
The effect of vanadium oxide as support and promoter on supported rhodium catalysts on the CO hydrogenation has been investigated at 0.15 and 4.0 MPa. Rh/V,O, reduced at 723 K has a good selectivity toward oxygenated products, especially C,-oxygenates, but has a low activity added as a promoter to catalysts consisting and stability. Vanadium oxide of rhodium supported on silica and alumina show...
