Abstract

Promoting effects of Lanthanum oxide on the NiO/CeO₂ catalyst for hydrogen production by autothermal reforming of ethanol were investigated. The effects of La increased the specific surface area, stabilized the NiO phase and led to the high dispersion of Ni in active LaNiO₃ phase. The carrier CeO₂ provided big specific surface area for effective EATR reaction, promoted the H₂ production by accelerating the oxygen migration in the catalyst surface via the Ce^{4 +} ↔ Ce^{3 +} transformation. Consequently, the optimized Ni₁La₁O_y/10CeO₂ catalyst achieved 100% X_EtOH, 69.3% S_H2 at 600 °C and high stability at 550 °C.
