Ni Catalyst of Partial Oxidation of Methane to Syngas

Ni/α-Al2O3 catalysts with different Ni content for the partial oxidation of methane to syngas,and the promoter effect of Ce to Ni/α-Al2O3 catalysts were investigated.Ammonia alumina nitrate and nickel nitrate was taken as raw material by the method of chemical precipitation to synthesize Ni/α-Al2O3 gelatin,which was calcined to attain nanosized Ni/α-Al2O3 catalyzer powders in the high temperature.And we used the fixed bed reactor to appraise the catalyst,simultaneity the catalyst structure was tested by XRD,TPR experimental.The result indicates that the Ni/α-Al2O3 catalyzer of 8%(mass fraction)Ni content had the optimal activity.Furthermore CeO2 significantly improved the activity,the selectivity and the stability under definite reaction conditions.
