CO2Methanation over Ru and/or Ni based catalysts Osupported on KIT-6, Al2O3and CeO2

In this study, three supports, mesoporous silica (KIT-6), alumina (Al ₂ O ₃ ) and ceria (CeO ₂ ) were synthesized. The wet impregnation technique was used in order to add an active phase of ruthenium (Ru-1%), nickel (Ni-15 ^% ), or a combination of the two metals (Ni-Ru) on each of the stabilized supports. The catalysts obtained were calcined at 550°C and then characterized by XRD and H ₂ -TPR. The catalysts were evaluated for their activity in the CO ₂ methanation reaction in the temperature range 150-350°C.
