Abstract

Abstract: The loading amount of ZrO2 in NiO/ZrO2-Al2O3 affected the reactivity an d stability of the catalyst. When the loading of ZrO2 was 0.60 g/g(Al2O3) , the dispersion of NiO reached the threshold value and the catalyst displayed a high catalytic activity and better stability.

Key words: zirconium dioxide, alumina, nickel, nanometer, composite support, dispersion state, carbon dioxide, methane
