Abstract

2-step methane reforming, consisting of syn-gas production and water splitting step, was carried out over Cu-ferrite/$ZrO_2$. To improve the reactivity over Cu-ferrite/$ZrO_2$ presenting low reactivity in 2-step methane reforming, the addition of Ni was considered. As the results, the added Ni to Cu-ferrite/$ZrO_2$ improved the reactivity in syn-gas production step. However, (Cu, Ni) ferrite/$ZrO_2$ showed carbon deposition in syn-gas production step when an excess Ni was added. Furthermore, (Cu, Ni) ferrite/$ZrO_2$ showed the high durability without the deactivation of the medium during repeated ten cycles, although it showed more deposited carbon than the medium without Ni.
