Fossil natural gas

The carbon dioxide reforming of methane has attracted academic and industrial interest, since it produces synthesis gas with a H2/CO ratio closed to 1, which is more suitable for methanol and Fischer-Tropsch synthesis compared to the steam reforming of methane providing synthesis gas with a H2/CO ratio = 3. This reaction is of particular importance for the valorization of C02-rich fossil natural gas but also for the transformation of biogas extensively produced by various anaerobic waste treatments [1]. The production of synthesis gas from CH4 and CO2 is highly endothermic (Eq. (22.1)), the reaction equilibrium is influenced by the simultaneous occurrence of the reverse water-gas shift reaction (RWGS) (Eq. (22.2)).
