The test bench was designed to test catalytic materials (powder or pellets) in a fixed-bed reactor for producing synthetic fuels (i.e., methane, methanol, dimethyl-ether and hydrocarbons) via thermochemical CO2 hydrogenation. The test bench can operate in a wide temperature range (RT – 550 °C) and pressure (1 – 30 bar) by using CO2, CO, H2, CH4 and N2. The analytical setup consists in an on-line Emerson X-Stream gas analyser and an Agilent Technologies 7890B gas-chromatograph equipped with a thermal conductivity detector (TCD) and a flame ionization detector (FID). The test bench is suitable for investigating catalytic performances in terms of activity and stability or performing kinetic studies.
