N2 - The reverse water gas shift (rWGS) reaction represents a key technol-ogy to realize an end-to-end power-to-liquid process chain. In this work, experi-mental tests of a nickel catalyst are reported. The influence of operating temper-ature (650-950 °C), pressure (ambient pressure up to 6 bara) and gas hourly space velocity (6000-40 000 h-1) on the conversion of CO2 and hydrogen is investi-gated. The results of this experimental evaluation show that the rWGS reaction favors high temperatures and low pressures. Thermodynamic equilibrium is ap-proached with the used catalyst. Higher gas hourly space velocities favor the rWGS reaction and inhibit methane formation.
