摘　　要：为了适应未来加氢站的需求,在分析现有供氢技术优缺点的基础上,对分布式制氢系统催化过程和化工过程进行“流程再造”。通过开发新型甲醇制氢催化剂,提高了甲醇制氢的反应效率,减少反应器体积。新型催化氧化催化剂具有低温活性好、高温稳定性好的优点。采用微通道技术对分布式制氢系统中的换热过程进行强化,实现了装置的小型化。甲醇重整-催化氧化耦合体系充分利用吸热-放热反应特性,实现了系统能量的闭环利用。所开发的分布式甲醇制氢系统在国内首次开展了加氢站制氢加氢一体站示范,分布式甲醇制氢示范装置占地面积仅64 m^(2),生产1 kg燃料电池级氢气消耗7.37 kg甲醇,为我国加快构建安全、稳定、高效的氢能供应网络提供了可复制、可推广的经验,对降低氢气成本、大规模推广应用具有积极意义。To satisfy the hydrogen demand for hydrogen refueling stations,based on the analysis of the advantages and disadvantages of the existing hydrogen supply system,the catalytic process and chemical process of the distributed hydrogen production system were“re-engineered”to form a new distributed hydrogen production system.The development of a new type of catalyst for hydrogen production from methanol improved the reaction efficiency and reduced the reactor volume.The new catalytic oxidation catalyst has the advantages of high activity at low temperatures and good stability at high temperatures.The micro-channel technology was used to strengthen the heat transfer process in the distributed hydrogen production system,and the miniaturization of the device was realized.The coupling system of methanol reforming and catalytic oxidation made full use of the characteristics of endothermic-exothermic reaction and realized the closed-loop utilization of system energy.The distributed hydrogen production system developed in this paper was first developed in China,and the integrated hydrogen refueling station with the production of hydrogenation was demonstrated.The covered area of the distributed methanol hydrogen production demonstration unit was only 64 m^(2),and the methanol consumption of 1 kg fuel cell grade hydrogen was 7.37 kg.It provides a replicable and extensible experience for China to construct a safe,stable,and efficient hydrogen supply network,and has a positive significance for reducing the cost of hydrogen and promoting its application on a large scale.
