The Role of Alkali and Alkaline Earth Metals in the CO2 Methanation Reaction and the Combined Capture and Methanation of CO2 [PDF]
Catalysts, 2020 CO2 methanation has great potential for the better utilization of existing carbon resources via the transformation of spent carbon (CO2) to synthetic natural gas (CH4). Alkali and alkaline earth metals can serve both as promoters for methanation catalysts and as adsorbent phases upon the combined capture and methanation of CO2.

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 ...

Different Reactor Configurations for Enhancement of Co2 Methanation
Environmental Research, 2023 Greenhouse gas emissions are a massive concern for scientists to minimize the effect of global warming in the environment. In this study, packed bed, coated wall, and membrane reactors were investigated using three novel nickel catalysts for the methanation of CO2. CFD modelling methodologies were implemented to develop 2D models.

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.
