微反应器内低碳醇水蒸气重整制氢研究进展

氢气是一种清洁、高效且在未来极具潜力替代化石燃料的可再生能源,但目前氢能在运输、储存过程存在的"氢脆"问题制约了其发展。在微反应器内连续、安全且高效进行低碳醇水蒸气重整制氢可为车载燃料电池和分布式加氢站供氢,对氢能替代化石燃料具有促进作用。对低碳醇水蒸气重整制氢反应机理、重整催化剂、微反应器内催化剂载体板以及低碳醇水蒸气重整制氢微反应器的研究进展进行了综述,指出了该制氢技术目前存在的问题,并针对性提出了未来该技术的研究方向。

Research progress of hydrogen production by steam reforming of low carbon alcohols in microreactor

Hydrogen is a clean,high-efficiency and renewable energy that has the greatest potential to replace fossil fuels in the future,but the“hydrogen embrittlement”problem in the transportation and storage process restricts its development.The continuous,safe and efficient hydrogen production by steam reforming of low carbon alcohols in microreactor can supply hydrogen for vehiclemounted fuel cells and distributed hydrogen refueling stations,and promote hydrogen energy to replace fossil fuels.The research progress of reaction mechanism,reforming catalyst,catalyst carrier plate in microreactor and hydrogen production by steam reforming of low carbon alcohols microreactor were reviewed.And the existing problems of the hydrogen production technology were pointed out.Finally,the future research direction of the technology were proposed.
