Molybdenum Carbide Supported Platinum Catalysts for Water-Gas Shift: A Theoretical and Experimental Investigation
Introduction Early transition metals carbides are catalytically active in a variety of reactions, such as isomerization reactions, hydrogenation reactions, water-gas shift (WGS), hydrocarbon steam reforming, etc. [1]. Our group recently developed a method to load metal catalysts onto high surface area carbide and nitride supports, and demonstrated that Pt supported on Mo carbide (Mo2C) possesse...
متن کاملNO reduction by CH4 in the presence of excess O2 over Pd/sulfated zirconia catalysts
The selective catalytic reduction (SCR) of NO by methane in the presence of excess oxygen has been studied on a series of Pd catalysts supported on sulfated zirconia (SZ). This support is not as sensitive to structural damage by steaming as the acidic zeolites, such as H-ZSM-5 and H-Mor. In previous studies, it was shown that this type of acidic zeolites are able to stabilize Pd2+ ions and prom...
متن کاملn-Butane Isomerization Catalyzed by Sulfated Zirconia Nanocrystals Supported on Silica or γ-Alumina
Supported sulfated zirconia catalysts with zirconia contents of 10, 20 and 50 wt% were prepared by impregnation of SiO2 and γ-Al2O3 supports with H2SO4/Zr(SO4)2 solutions followed by calcination at 923 K. The catalysts were characterized by X-ray diffraction, extended X-ray absorption fine structure measurements, thermal analysis, UV–vis spectroscopy, and electron microscopy. Tetragonal zirconi...
متن کاملSulfated zirconia and tungstated zirconia as effective supports for Pd-based SCR catalysts
It is now well established that even though Pd supported on acidic zeolites is highly selective for CH4-SCR, zeolitic structures are susceptible to dealumination under hydrothermal environments. In this contribution, we have investigated the ability of non-zeolitic acidic materials to promote the SCR selectivity and stability in the presence of H2O and SO2. The results of catalytic activity mea...
متن کاملKinetic Study and Modelling of n-Heptane Reforming Process over Pt/Zr-HMS/HZSM-5 Composite Catalysts
Pt/Zr(x)-HMS/HZSM-5 catalysts with various Si/Zr ratios (as x) were used for investigation of the kinetics of n-heptane reforming process under 350 - 450 oC reaction temperature, 35 to 80 ml min-1 flowing rate of hydrogen and 2 to 5 ml h-1 flowing rate of n-heptane. In the present work, two kinetics (power law and Langmuir - Hinshelwood) models were selected and examined to describe the kinetic...
