The commercial Fe based catalyst was provided by Clariant AG and reduced with a gas flow of 0.03 mol/min of H2 (Linde, 5.0) and N2 (Linde, 5.0) in a molar ratio of 3 at 450 °C and 80 bar (g) for 12 h prior to catalytic experiments. Silicon carbide (SiC, supplier) was used as inert material. The sorbent was prepared by wet impregnation of AC with MnCl2 with a nominal mass loading of 30 wt.-%. Therefore, 1.5 g of anhydrous MnCl2 (Sigma Aldrich, 98 %) was dissolved in Ethanol (EtOH, Carl Roth, 99.5%) and mixed with 3.5 g of AC. The wet sorbent was dried in a rotary evaporator at 40 °C and 60 mbar for 3.5 h. To ensure a low EtOH and H2O content of the sample, it was subsequently dried in a vacuum oven for 12 h at 75 °C and 20 mbar before placing it inside the reactor. All solid material were fractionated in a particle size range of 0.25 mm < 𝑑 < 0.5 mm before usage by sieving.
