Hydrogen from Biomass Degradation Production by Aqueous-Phase Reforming: An Overview on the Catalysts

摘要

Hydrogen production is very important in the field of renewable energy, especially in the development of fuel cells. Since Dumesic proposed that hydrogen production by aqueous-phase reforming (APR) of biomass in 2002, great progresses have been made in this research field, especially in the exploration and screening of catalysts. This paper gives an overview on the catalysts using in APR reaction and the activity on different model compounds. Noble metal catalysts and Ni-based catalysts were the main ones suitable for the catalytic process. Besides, Ce, Co, Zn, and other metallic catalysts, as well as bi-functional catalysts, were also tested for their activity in the hydrogen production. Among these catalysts, Pt-based catalysts were effective for hydrogen relatively, but the activity of each catalyst was different due to the effect of different supports. Bi-functional catalysts showed higher activity compared with the monomeric metal ones.
