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 کاملEffect of acidity and physical properties of nanozeolite catalyst on hydrocracking of vacuum gas oil
In this study, beta nanozeolite, ultra-stable Y zeolite (USY) and amorphous silica-alumina (ASA) were synthesized. These compounds were used as the support of hydrocracking catalyst. Ni-Mo/beta zeolite-ASA and Ni-Mo/USY zeolite-ASA catalysts were prepared by the impregnation method. The samples were characterized with X-Ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM)...
متن کاملPreparation for Pt-Loaded Zeolite Catalysts Using w/o Microemulsion and Their Hydrocracking Behaviors on
Pt-loaded β-type zeolite catalysts with constant Pt content (0.11 wt.%) and similar pore structure were prepared using a water-in-oil (w/o) microemulsion. The effect of Pt particle synthesis conditions using microemulsion (a type of Pt complex-forming agents and the molar ratio of complex-forming agent to Pt4+) on loaded Pt particle size was investigated. The Pt particle size of the Pt catalyst...
متن کاملLow-temperature SCR of NO with NH3 over USY-supported manganese oxide-based catalysts
A series of catalysts of manganese oxide, manganese–cerium and iron–manganese oxide supported on USY (ultra-stable Y zeolite) were studied for the low-temperature selective catalytic reduction (SCR) of NO with ammonia in the presence of excess oxygen. It was found that MnOx/USY have high activity and high selectivity to N2 in the temperature range 80–180 8C. The addition of iron and cerium oxid...
