可再生生物质制氢是未来氢能的主要来源，涉及到化学制氢和生物制氢．生物质化学制氢技术包括生物质气化、热解、超临界转化等常规热化学法制氢和生物质解聚液相产物的蒸汽重整、水相重整、自热重整和光催化重整制氢等技术.对以上生物质制氢方法进行了综述，对反应条件、反应机理、催化剂使用、技术经济性及各自存在的优缺点进行分类整理与比较.认为生物质气化制氢及热解制氢技术的发展较成熟，可以实现规模化生产，但是制氢的选择性和产氢率不高；生物质液相产物催化重整制氢技术更适合较大规模的集中制氢，转化率和产氢率高，但技术途径复杂.对生物质制氢技术进行了展望. |

Hydrogen from biomass is considered to be an important future hydrogen supplier. It usually contains chemical and biological conversion. Conventional thermo-chemical conversion covers gasification, pyrolysis and supercritical process，and catalytic reforming includes steam reforming, aqueous-phase reforming, auto-thermal reforming and photocatalytic reforming process using the liquid products derived from biomass depolymerization. These processes that mentioned above were overviewed and their operating conditions, reaction mechanism, catalysts, economic-technical advantages and disadvantages were compared. Gasification or pyrolytic conversion is approaching industrial scale, but hydrogen selectivity and yield are far from satisfactory. Catalytic reforming process of the biomass-derived liquid product may be applicable to scale-up with high hydrogen selectivity and yield, but technological process is still under development. The future developing direction of biomass to hydrogen development was pointed out. |
