The Effects of the Preparation Method on the Reforming Activity of Nickel Catalysts

We have studied, by XRD, TPR and performance evaluation, the effects of the preparation method on catalytic activities of conversion of CH4 with CO2 to syngas over NiO/γ-Al2O3 catalysts. Under the present experimental conditions, the catalyst with NiO/γ-Al2O3(ω = 0. 113), which was obtained through impregnation process and calcination temperature 400℃ , exhibited its good catalytic activity during the conversion of CH4 and CO2, when the reaction temperature was 750℃ and the space velocity was 2500h-1. The problem of catalyst's resistance to the carbon deposition has also been preliminarily discussed in the paper.
