Techno-Economic Evaluation of Biological and Fluidised-Bed Based Methanation Process Chains for Grid-Ready Biomethane Production

Frontiers in Energy Research, 2022
Three different power-to-methane process chains with grid injection in two scales (1 MWel and 6 MWel) were analysed regarding their investment and operation cost. The process chains were based on biological or catalytic bubbling fluidised bed methanation

Oxidation and assimilation of atmospheric methane by soil methane oxidizers [PDF]

Applied and Environmental Microbiology, 1997
The metabolism of atmospheric methane in a forest soil was studied by radiotracer techniques. Maximum (sup14)CH(inf4) oxidation (163.5 pmol of C cm(sup-3) h(sup-1)) and (sup14)C assimilation (50.3 pmol of C cm(sup-3) h(sup-1)) occurred at the A(inf2) horizon located 15 to 18 cm below the soil surface. At this depth, 31 to 43% of the atmospheric methane

Ammonia Methanation of Carbon Dioxide with a Hybrid Catalyst

Journal of Chemical Engineering of Japan, 2023
Ammonia methanation is a reaction that synthesizes methane directly from carbon dioxide and ammonia. The Sabatier reaction, which synthesizes methane by hydrogenating carbon dioxide, requires a cooling facility in the reactor due to its large heat value.

Consumption of Methane by Soils [PDF]

Environmental Monitoring and Assessment, 1994
Measurements of the methane flux and methane concentration profiles in soil air are presented. The flux of methane from the soil is calculated by two methods: a) Direct by placing a static open chamber at the soil surface. b) Indirect, using the (222)Rn concentrations profile and the (222)Rn flux in the soil surface in parallel with the methane ...
