Abstract

The effect of addition of strontium in Co based catalysts during CO₂ reforming of methane was investigated in the temperature range 500-700°C. The Co/γ-Al₂O₃ supported catalysts with strontium as a promoter (0-2.25wt%) were prepared by incipient wet impregnation method. Numerous techniques such as N₂ adsorption-desorption isotherm, H₂ temperature-programmed reduction (TPR), temperature-programmed desorption (TPD), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Transmission Electron Microscopy (TEM), pulse chemisorption and temperature-programmed oxidation (TPO) were applied for characterization of fresh and spent catalysts. The results of characterizations and catalyst activity test revealed that introduction of Sr in Co/γ-Al₂O₃ catalyst had significant effect on stability and coke suppression. The Sr addition improves the metal-support interaction as well as enhances the Lewis basicity of the catalyst. The improvement in basicity helps the chemisorption and dissociation of CO₂ over the catalyst which in turn reduces carbon deposition.
