Nickel and ruthenium promoted by ceria were compared as catalyst active phase for the production of synthetic natural gas in a 1 kW fixed-bed reactor (49 cm in length and 3 cm in diameter). Both catalysts were tested in a broad range of conditions: 250–450 °C, 8000–16000 h−1 GHSV, 3.5–5.5H2/CO2 ratio, and atmospheric pressure. The Ni-based catalyst presented higher CO2 conversion and lower reduction of BET area and metal dispersion after utilization. Two kinetic models were elaborated according to the performance of the catalysts in this reactor. The minimum mean squared error between the kinetic model and experiments was 3.0% for the Ru-based catalyst and 1.4% for the Ni-based catalyst. The kinetic model of the Ni-based catalyst was implem...
