Carbon dioxide reforming Carbon dioxide reforming Carbon dioxide reformation (also known as dry reformation) is a method of producing synthesis gas (mixtures of hydrogen and carbon monoxide) from the reaction of carbon dioxide with hydrocarbons such as methane. Synthesis gas is conventionally produced via the steam reforming reaction. In recent years, increased concerns on the contribution of greenhouse gases to global warming have increased interest in the replacement of steam as reactant with carbon dioxide. The dry reforming reaction may be represented by: Thus, two greenhouse gases are consumed and useful chemical building blocks, hydrogen and carbon monoxide, are produced. A challenge to
ExoMars Trace Gas Orbiter be a strong indication that biological processes are involved. However, if methane is found in the presence of gases such as sulfur dioxide (), that would be an indication that the methane is a byproduct of geological processes. The nature of the methane source requires measurements of a suite of trace gases in order to characterise potential biochemical and geochemical processes at work. The orbiter has very high sensitivity to (at least) the following molecules and their isotopomers: water (), hydroperoxyl (), nitrogen dioxide (), nitrous oxide (), methane (), acetylene (), ethylene (), ethane (), formaldehyde (), hydrogen cyanide
