The Ni/Al₂O₃ catalysts were prepared by two impregnation methods:common and promoted with support salt, for CH₄/CO₂ reforming and studied by using TPR, TPD, TPMC(Temperature programmed methane decomposition carbon deposition) and activity test techniques. The results showed that the coke formation of the catalysts promoted with support salt(aluminium nitrate) was reduced to one sixth and the dispersion increased by 72.7% in comparison with catalyst prepared by common impregnation method. The interactions between Ni and Al with O on the surface of the support salt promoted catalyst appeared stronger.
