The feed composition was realized by adding the different gas mixtures listed in chapter 2.1 through mass flow controllers. The composition of the output was monitored via GC with a FID analyzer. Detailed Information regarding the GC Method and the column can be found in the supporting information (GC program, Table ). In each experiment the temperature is varied from 30 to 90 °C in 10 °C steps. Every temperature step was held for 100 min.
