Abstract
Proces katalitične metanacije obnovljivega vodika in ogljikovega dioksida v biometan predstavlja zelo pomembno rešitev pri zmanjševanju izpustov toplogrednih plinov in hkrati varno uporabo vodika, katerega proizvodnja zaradi vse večje rabe obnovljivih virov energije in implementacije elektrolize neprestano narašča. Proces katalitične metanacije z uporabo katalizatorja na osnovi niklja je možno nadgraditi s sistemom za sprotno spremljanje procesa preko merjenja temperaturnih gradientov znotraj metanacijskega reaktorja. Osredotočili smo se na razvoj ter optimizacijo eksperimentalnega sistema za opazovanje katalitične metanacije z uporabo infrardeče termografije. Z uporabo izdelanega eksperimentalnega sistema smo izvedli meritve spremenljivega temperaturnega polja med procesom katalitične metanacije. S pomočjo infrardeče termografije smo analizirali delovanje reaktorja pod različnimi temperaturnimi pogoji, z uporabo različnih katalizatorjev in pretokov plinov, ki sodelujejo v reakciji.

Title:Monitoring of methanation process on pellets with nickel catalyst through high-resolution IR thermography
Abstract:
The catalytic methanation process of renewable hydrogen and carbon dioxide into biomethane is seen as a crucial solution for reducing greenhouse gas emissions and for the safe utilization of hydrogen, which is produced increasingly due to the growing use of renewable energy sources and the implementation of electrolysis. The catalytic methanation process, when using a nickel-based catalyst, can be enhanced with a system designed for continuous monitoring through the measurement of temperature gradients inside the methanation reactor. Focus was placed on the development and optimization of an experimental system intended for the observation of catalytic methanation through infrared thermography. Using the developed experimental system, measurements of a variable temperature field during the catalytic methanation process were conducted. The operation of the reactor under various temperature conditions, employing different catalysts and gas flows involved in the reaction, was analyzed using infrared thermography.

Keywords:methanation, hydrogen, carbon dioxide, IR thermography, NiO catalyst, gas chromatography
