Abstract
Katalitična metanacija lahko posredno rešuje problematiko hranjenja viškov električne energije in višanja koncentracije atmosferskega ogljikovega dioksida, zaradi česar ima velik potencial. Zaključna naloga se posveča iskanju vpliva različnih procesnih temperatur in različnih koncentracij vstopnih plinov na učinkovitost procesa metanacije ob prisotnosti katalizatorja iz nikljevih in CuZnGa mikrodelcev. IR termografija in plinska kromatografija sta pokazali višjo aktivnost katalizatorja iz CuZnGa mikrodelcev v primerjavi s katalizatorjem iz nikljevih mikrodelcev. Katalizator iz CuZnGa mikrodelcev je optimalen za višje temperaturno območje (>450°C), medtem ko nikljevi mikrodelci dosežejo najvišjo aktivnost pri temperaturi 410 °C. Nikljev katalizator na osnovi alumine je aktivnejši od nikljevega katalizatorja z mikrodelci in dosega temperaturni optimum pri 370 °C.

Title:Catalytic methanation in the presence of a nickel and CuZnGa microparticle catalyst
Abstract:
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.

Keywords:methanation, methanation reactor, IR thermography, gas chromatography, nickel catalyst, CuZnGa catalyst
