英文摘要	ceo2 modified ni/al2o3 catalysts were developed for synthetic natural gas (sng) from bio-syngas methanation. physiochemical properties of the ceo2 modified ni/al2o3 catalysts were characterized by n-2 physical adsorption (bet), scanning electron microscopy (sem), temperature-programmed reduction of hydrogen (h-2-tpr), x-ray diffraction (xrd) and thermo gravimetric analyzer (tga). the bio-syngas methanation tests showed that adding 60 wt.% of ceo2 in the ni/ceo(2)eal(2)o(3) catalyst presented excellent bio-syngas methanation performances (91.6% carbon oxides conversion with 92% ch4 selectivity) at low temperature (350 degrees c). the characterization results indicated that adding of ceo2 into ni/al2o3 strengthened the nio-ceo2 interaction via the weakening of the interaction between ni species and al2o3, facilitating the separation of nio from nial2o4. the optimal ceo2 content of 60 wt.% was obtained to disperse well ni species and increase active metallic ni sites, promoting the catalytic performances for bio-syngas methanation to sng.
