Abstract
Methanization of carbon monoxide‐rich gases for energy‐transport. The partners of the NFE project (Nukleare Fernenergie, Remote nuclear energy) – Kernforschungsanlage Jülich GmbH (Germany) and Rheinische Braunkohlenwerke AG, Köln (Germany) – in collaboration with Haldor Topsøe A/S, Copenhagen (Denmark), have investigated various problems of the methanization of synthesis gases rich in carbon monoxide. Preliminary results obtained from trial operations with the pilot‐scale methanization plant ADAM I at KFR Jülich and from the catalyst‐development project at Haldor Topsøe A/S are reported. A detailed account is given of the catalyst investigations carried out on the Haldor Topsøe pilot plant for the further development of the TREMP process for SNG manufacture and of the complementary catalyst investigation in the NFE project at the Union Rheinische Braunkohlen Kraftstoff AG and the Kernforschungsanlage Jülich GmbH for the optimization of the methanization process in the remote energy system EVA‐ADAM. In the pilot plant ADAM I, a three‐stage methanization process with product gas recycling and maximum temperature of 600 °C utilizing synthesis gas from methane vapour reforming (EVA) has been demonstrated for the first time. In further experiments to be carried out with ADAM I the influence of operating irregularities on the behaviour of the methanization plant and the dynamics of the remote energy system will be investigated, data for the preparation of mathematical models collected, new components tested, and the process of methanization optimized.
