000162888 5203_ $$aThe production of synthetic methane is crucial for the energy transition in hard-to-electrify industries. This study assesses the reactor filler (Al2O3 and SiC) and operating pressure (1 and 4 bar) effects on methane performance of a commercial Ru-Al2O3 catalyst. Three catalytic methanation parameters are tested over a wide range: temperatures (200–450 °C), gas hourly space velocities (8000–120,000 h−1), and H2/CO2 molar ratios (3.5–5.5). Experiments are conducted in two pilot plants located at the Universidad de Zaragoza and the Silesian University of Technology. Results demonstrate a high level of reproducibility between the two pilot plants, using Al2O3 filler at 1 bar. Additionally, a kinetic model is validated with experimental measurements, showing an error margin of ±5 % between the model and experimental data. Regarding the effects of operational pressure and reactor filler, the best carbon conversion results are obtained with Al2O3 filler at 4 bar (up to 98 %). For both reactors, a 5 % reduction in carbon conversion is observed at 450 °C for SiC filler. Methane selectivity remains above 99 % in all cases, except for SiC filler at 1 bar (90 %). However, SiC filler shows better thermal diffusion, facilitating operational control.
