Abstract

The nickel based catalysts were prepared by the method of impregnation. The influence of the Ni loading, the calcination temperature, the reduction temperature, the promoter on the catalyst performances in the CH4-CO2 reforming reaction was investigated. The results indicate that the Ni/SiO2 catalyst with the 10%Ni loading and calcined at 773 K for 2 h and reduced at 723 K for 2 h exhibited the best activity in the reaction, and the conversion of CH4, CO2 and total carbon were 67.27%, 67.21%, 67.24%, respectively. The influence of the Cr2O3 promoter on the properties of the catalysts was investigated. The results show that the carbon deposition on the Ni/SiO2/Cr2O3 catalyst was decreased, and the activity of the catalyst was enhanced by adding Cr2O3 promoter in the Ni/SiO2 catalyst. The conversion of CH4, CO2 and total carbon reached 69.86%, 70.47% and 70.20% on the Ni/SiO2/Cr2O3 catalyst with the 10% Ni and 1.0% Cr2O3 calcined at 773K for 2 h and reduced at 723K for 2 h in the CH4-CO2 reforming reaction. The carbon deposition on Ni/SiO2/Cr2O3 catalyst was decreased 26.35% compared to that on Ni/SiO2 catalyst.
