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 کاملCobalt Catalysts Decorated with Platinum Atoms Supported on Barium Zirconate Provide Enhanced Activity and Selectivity for CO2 Methanation
A perovskite-structured barium zirconate, BaZrO3 (BZ), support is demonstrated to enhance the activity, relative to γ-Al2O3, of Co nanoparticle catalysts decorated with Pt for CO2 methanation. The CO2 methanation reaction may play a central role in both CO2 utilization and energy storage strategies for renewable energy. These catalysts require cooperative hydrogen transport between the supporte...

متن کاملNickel-induced morphology change of mesostructured alumina with enhanced catalytic activity for selective CO methanation.
Nickel-induced morphology change of mesostructured alumina with amorphous walls to bayerite tetrahedra when treated in water, and then to γ-alumina with worm-like mesopores topologically after it was calcined at 400 °C is reported. The catalytic activity for selective CO methanation increased significantly after this treatment.
متن کاملDinuclear metal catalysts: improved performance of heterodinuclear mixed catalysts for CO2–epoxide copolymerization†
Some of the most active catalysts for carbon dioxide and epoxide copolymerization are dinuclear metal complexes. Whilst efficient homodinuclear catalysts are known, until now heterodinuclear catalysts remain unreported. Here, a facile, in situ route to a catalyst system comprising amixture of homoand heteronuclear Zn–Mg complexes is presented. This catalyst system shows excellent polymerization...
