Abstract: 
Natural gas is an important commodity in the European energy market. A promising concept
for the production of synthetic natural gas on a carbon neutral basis is presented by the
gasification of biogenic residues and the further reaction to a methane-rich gas. This paper
investigates the thermodynamics of methanation for different product gas compositions of the
dual fluidized bed gasification technology. A complete methanation of the carbon oxides is
possible by the utilization of a product gas from the sorption enhanced reforming process. For
product gases from conventional or carbon dioxide gasification, only partial methanation of
carbon monoxide occurs. Additionally, proper handling of carbon depositions through
adjustments of feed gas composition and operational parameters in the methanation reactor are
essential. Temperature and pressure variations allow a thermodynamically optimized
operation, which can reduce energy costs for compression or lower the amount of gas
upgrading for grid feed-in. Vice versa, it is shown that the feed gas can be optimally adjusted
to the operational parameters of the methanation via the sorption enhanced reforming process.
