20.500.12556/RUL-139362 Razvoj eksperimentalne proge za spremljanje katalitične metanacije z infrardečo termografijo Development of an experimental setup for infrared thermographic observation of catalytic methanation Biometan, pridobljen s pomočjo katalize zelenega vodika in ogljikovega dioksida je mogoče vključiti v obstoječe energetsko procesne sisteme. V zadnjem času, ko je želja po prehodu na zeleno in trajnostno neodvisno energetsko gospodarstvo vedno večja, se raziskave na tovrstnih tehnologijah vedno bolj širijo. Za voljo slabšega poznavanja toplotnih pojavov pri poteku metanacije v katalitskih reaktorjih, v delu obravnavamo zasnovo in izdelavo eksperimentalne proge za spremljanje katalitične metanacije z infrardečo termografijo. S pomočjo razvite eksperimentalne proge smo izvedli meritve nestacionarnega temperaturnega polja pri procesu katalitične metanacije. Preučili smo delovanje zasnovanega reaktorja pri različnih temperaturnih stanjih, pretokih reaktantskih plinov in katalizatorjih. Zaradi procesa metanacije se temperatura posameznih peletov, kjer poteka reakcija poveča, kar lahko učinkovito spremljamo s pomočjo infrardeče termografije. Biomethane produced by catalysis of green hydrogen and carbon dioxide can be incorporated into existring energy processing systems. Recently, as the desire to transition to a green and sustainably independent energy economy grows, research on such technologies is growing. Thermal phenomena during methanation in catalytic reactor is not well researched yet, therefore in our work, we examine the process of developing and building experimental setup for infrared thermograohic observation of catalytic methanation. With the help of a developed experimental setup, we performed measurement of the unsteady temperature field during the catalytic methanation process. We examined the operation of the designed reactor at different temperature conditions, reactant gas flows and type of catalysts. Because of methanation process the temperature of individual pelets of catalysts where reaction takes place increases, which can be effectively monitored using infrared thermography. metanacija vodik ogljikov dioksid katalitični reaktor NiO katalizator methanation hydrogen carbon dioxide catalytic reactor NiO catalyst true false false [M.
