Design and Construction of a New Reactor for Flexible Biomethanation of Hydrogen

The increasing share of renewable electricity in the grid drives need for sufficient storage capacity. Especially seasonal storage, power-to-gas can be a promising approach. Biologically produced methane from hydrogen surplus used to substitute natural gas existing infrastructure. Current reactor types are not or poorly optimized flexible methanation. Therefore, this work proposes new type with plug flow (PFR) design. Simulations COMSOL Multiphysics ® showed properties operation laminar flow. An experiment was conducted support simulation results and determine fraction novel reactor, which measured 29%. Based on these simulations experimental results, constructed as 14 m long, 50 mm diameter tube meandering orientation. Data processing established, step performed. In addition, kLa 1 h−1 determined. revealed that outcomes fractions line theoretical simulation. design shows methanation will tested.
