The Kinetics of Methanation on Nickel Catalysts
An empirical rate equation was obtained for the methanation kinetics catalyzed by MCR-2X, a commercial catalyst prepared by Haldor-Topsoe. The studies were carried out in a fixed-bed reactor under differential conditions, and in a gradientless recycle reactor (Berry) over a range of total pressures, reactant concentractions (H2/CO ratios), and temperatures. The kinetics of methanation were foun...
متن کاملA comparative study on the kinetics of carbon dioxide methanation over bimetallic and monometallic catalysts
In this paper, Ni/Al and La-Ni/Al catalysts were prepared with a co-impregnation method and employed in carbon dioxide methanation reaction. The catalytic results showed that the catalyst with (10wt.%) of lanthanum and (20wt.%) nickel had the highest activity at low temperatures in CO2 methanation and the La-Ni/Al catalysts changed the reaction path by lowering its activation energy and consequ...

15 صفحه اولStudy of HMS Modified ZrO2 Supported Platinum Catalysts for Toluene Removal: Catalytic Combustion and Kinetics Study
Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200 – 500 oC). Results show that Pt/Zr(x)-HMS performs more easily toluene oxidation. The kinetic data were fitted by the Power-law and Mars–van Krevelen kinetic models. The fitting res...
متن کاملHydrodeoxygenation of m-cresol over gallium-modified beta zeolite catalysts
Ga-modified H-Beta (Ga/HBEA) zeolites were evaluated and compared to other Ga-containing catalysts supported on SiO2 and ZSM-5 (MFI) for the hydrodeoxygenation of m-cresol, a model compound representative of lignin-derived phenolics. The products include toluene, benzene, xylene, light hydrocarbons, as well as phenol and other oxygenated compounds. The appearance of bicyclic compounds suggests ...
