Catalytic methanation can indirectly solve the problem of storing excess electricity and rising atmospheric carbon dioxide concentrations. Therefore it shows great potential. The final thesis focuses on the influence of different process temperatures and different inlet gas concentrations on the efficiency of the methanation process in the presence of a nickel and CuZnGa microparticle catalyst. IR thermography and gas chromatography showed a higher activity of the CuZnGa microparticle catalyst compared to the nickel microparticle catalyst. The CuZnGa microparticle catalyst is optimal for the higher temperature range (>450 °C), while the nickel microparticles reach their maximum activity at 410 °C. The alumina-based nickel catalyst is more active than the nickel microparticle catalyst and reaches a temperature optimum at 370 °C.
