摘要：

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 H-2 production by accelerating the oxygen migration in the catalyst surface via the Ce4+ <--> Ce3+ transformation. Consequently, the optimized Ni1La1Oy/10CeO(2) catalyst achieved 100% X-EtOH, 69.3% S-H2 at 600 degrees C and high stability at 550 degrees C.
