摘要: Abstract The transition metals (Cu, Co, and Fe) were applied to modify Ni/Ce 0.2 Zr 0.1 Al 0.7 O δ catalyst. effects of on the catalytic properties autothermal reforming methane investigated. Ni-supported catalysts characterized by XRD, TPR XPS. Tests in hydrogen showed that addition (Cu Co) significantly increased activity catalyst under conditions lower reaction temperature, Ni/Cu 0.05 Ce 0.65 was found have highest conversion CH 4 among all operation temperatures ranging from 923 K 1023 K. TPR, XRD XPS measurements indicated cubic phases x 1− 2 solid solution formed preparation process catalysts. Strong interaction exist between NiO solution. Cu improved dispersion NiO, inhibited formation NiAl , thus promoted .
