Hydrogenation of CO to hydrocarbons over iron nanoparticles supported on oxygen-functionalized multi-walled carbon nanotubes was studied in a fixed-bed U-tube reactor at 25 bar with a H:CO ratio of 3. Conversion of CO was approximately 35% yielding C-C products at 360 C with methane and CO as major products. The CO equilibrium conversion for temperatures in the range of 320 to 420C was analysed by using CHEMCAD simulation software. Comparison between experimental and simulated degrees of CO conversion shows that reverse water gas shift equilibrium had been achieved in the investigated temperature range and that less than 47% of CO can be converted to CO at 420C.
