Effect of twist angle in spiral-type Ru/CeO2 catalysts on CO2 auto-methanation performance
Journal of Chemical Engineering of Japan, 2023 This study aims to clarify the effect of twist angle in the spiral-type catalyst on CO2 auto-methanation (AM) performance. The spiral-type catalysts with different twist angles of 360°, 540°, 720°, and 1080° were constructed and investigated for their ...

A comparative study on the kinetics of carbon dioxide methanation over bimetallic and monometallic catalysts [PDF]
Hydrogen, Fuel Cell & Energy Storage, 2016 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 ...

Supported Catalysts for CO2 Methanation: A Review [PDF]
Catalysts, 2017 CO2 methanation is a well-known reaction that is of interest as a capture and storage (CCS) process and as a renewable energy storage system based on a power-to-gas conversion process by substitute or synthetic natural gas (SNG) production. Integrating water electrolysis and CO2 methanation is a highly effective way to store energy produced by ...

Low temperature CO2 methanation on hydrothermal synthesis of Ni-Ba/Sm2O3 catalysts
Sustainable Chemistry for Climate Action, 2023 A low temperature CO2 methanation is a thermodynamically favorable route to produce highly selective methane while preventing catalyst deactivation. Ni-Ba/Sm2O3 catalysts synthesized using one-pot hydrothermal method exhibited enhanced reducibility with ...

Sorption enhanced CO2 methanation
Physical Chemistry Chemical Physics, 2013 The transformation from the fatuous consumption of fossil energy towards a sustainable energy circle is most easily marketable by not changing the underlying energy carrier but generating it from renewable energy. Hydrocarbons can be principally produced from renewable hydrogen and carbon dioxide collected by biomass.
