WebBiogas is a mixture of methane, CO 2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment. The precise composition of biogas depends on the type of feedstock and the production pathway; these include the following main technologies: Web31 dec. 2024 · Methane pyrolysis in brief In methane pyrolysis, we produce hydrogen from natural gas with carbon - not CO2 - as a valuable by-product. It is affordable and will be commercially viable within a few years. The applications are numerous, e.g. steel additive, filler for car tyres, graphite, dye and soil improver.
