Abstract: Two processes (with cooled and adiabatic fixed bed reactors) for direct biogas methanation were assessed using detailed balances and rate-based models. The simulations show that they are capable to produce synthetic natural gas (SNG) in one or two steps without further upgrading after the reactors. The sizes for cooled beds are smaller than for adiabatic reactors due to heat transfer that reduces the needs for recirculation and allows for more favorable temperature profiles; although a more complex heat exchanger systems is then required for cooling.
