摘要:: 能源短缺和环境污染成为当今世界的两大难题，在双碳战略驱动下，氢能开发成为全球的研究热点。相比于利用一次能源制氢，重整有机废弃物制氢既可以减少化石能源利用、解决环境问题,又能产出清洁能源，是当前制备绿氢的重要途径之一。综述催化重整废弃食用油、废塑料、含氧挥发性有机化合物这3种典型有机废弃物制氢研究进展，着重阐述废弃物制氢工艺、催化剂的制备及性能，并针对催化重整有机废弃物制氢过程中三大关键问题：积碳与碳资源回收、催化剂高活性结构调控、催化剂再生与回收展开讨论。最后，基于该领域面临的挑战和发展趋势展望了重整有机废弃物制氢实用化、工业化的前景。

Abstract:: Energy shortage and environmental pollution have become the two major challenges nowadays, driven by the carbon-peak and carbon-neutral target, the develop of hydrogen energy has become global research hot spot. Compared with the usage of primary energy to produce hydrogen, reforming the huge amount of organic waste generated by industry and daily life to produce hydrogen can not only reduce the use of fossil energy, solve environmental problems, but also produce clean energy, which is one of the most important ways to prepare green hydrogen. This review reports the research progress on hydrogen production from the catalytic reforming of three typical organic wastes: waste cooking oil, waste plastics and oxygenated volatile organic compounds. The reforming process, catalyst preparation and hydrogen production performance are emphatically discussed. The key common problems of catalytic reforming of different wastes, such as the utilization of carbon deposit and carbon, regulation of catalyst structure with high activity, catalyst regeneration and recycling are also discussed. Finally, based on the challenges and development trends in this research field, the prospect of practical and industrial hydrogen production from reforming organic waste is analyzed.
