Abstract

Metal oxide (MgO, CaO, and La₂O₃) promoted Ni-Ce_0.8Zr_0.2O₂ catalysts have been applied for low-temperature steam reforming of methane (SRM), and the promoter effect was investigated. The addition of the metal oxides improved the basicity which enhances the resistance coke formation and catalytic activity. Among the prepared catalysts, the Ni-La₂O₃-Ce_0.8Zr_0.2O₂ catalyst exhibited high activity and stability at a very high gas hourly space velocity of 621,704 h⁻¹. This was mainly due to high dispersion of Ni, strong basicity of La₂O₃, and strong interaction between Ni and La₂O₃.
