Kinetic studies of CO2 methanation over a Ni/γ-Al2O3 catalyst.
The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...
متن کاملEnhancing catalytic activity and stability for CO2 methanation on Ni@MOF-5 via control of active species dispersion.
A novel, highly active catalyst Ni@MOF-5 showed unexpected activity at low temperature for CO2 methanation. The characterization results indicated that Ni was uniformly and highly dispersed over MOF-5. This catalyst showed high stability and almost no deactivation in long term stability tests up to 100 h.
متن کاملCarbon nanofibres coated with Ni decorated MoS2 nanosheets as catalyst for Vacuum Residue hydroprocessing
Catalysts based on functionalised carbon nanofibers (FCNF) coated with Ni-decorated MoS2 nanosheets were obtained by direct decomposition of ammonium thiomolybdate and nickel nitrate impregnated on the FCNF under controlled temperature conditions in inert atmosphere. The catalysts were characterised by X-ray Diffraction (XRD), N2 adsorption, Raman spectroscopy, temperature programmed reduction ...
متن کاملSyngas from CO2 Reforming of Coke Oven Gas: synergetic effect of activated carbon / Ni-γAl2O3 Catalyst
The CO2 reforming of coke oven gas for the production of synthesis gas has been studied over an activated carbon, an in-lab prepared Ni/Al2O3 catalyst and physical mixtures of both materials in different proportions (AC+Ni) at 800 oC. It was found that there are two possible coexisting reaction pathways: the direct dry reforming of methane (decomposition of methane followed by gasification of t...
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...
