The unit may be used for catalyst testing, e.g. for the conversion of synthesis gas (mixture of CO, H₂ and optionally CO₂) to methanol. It may also be used for CO₂ hydrogenation, propane dehydrogenation with CO₂, …. Depending on the process, the reactor system can be switched between low-pressure/high-temperature (17.5bar-850°C) and high-pressure/low-temperature (100bar-550°C). The setup uses only gas injection. The reaction effluents are analysed online using a TRACE-1310 GC analyser equipped with Rt-Ubond (FID), RTX-1 (FPD), Hayesep N and SC-ST (TCD 1), and RT-QBond and RT-MS 5A (TCD 2) columns. It can measure permanent gases (H₂, He) by TCD, sulphur compounds by FPD and dimethyl ether, methanol and other elements by FID.
