| 摘 要： | 生物乙醇重整制氢是氢能绿色供应的重要途径,其采用可再生能源为原料,运用成熟、高效的化工工艺,积极助力碳达峰、碳中和目标的实现。生物乙醇是已被广泛应用的化石燃料替代品,随着纤维素乙醇技术不断进步,生物乙醇生产不再受限于淀粉基原料。目前,生物乙醇重整能够以制氢和生物乙醇已有的产业化成果为基础,实现与现有氢能产业的快速链接。然而,乙醇中碳碳单键的存在对制氢催化剂开发提出了新的挑战。同时,钯膜反应器生产水平的显著提高又为制氢设备小型化和在线应用创造了机遇。未来,生物乙醇可通过加油站供应,氢气随产随用能够避免储运的安全隐患,生物乙醇重整燃料电池车有望在产业化的过程中实现对燃油车的无缝替代,具有广阔的市场前景和重大的战略意义。

| Abstract: | Bio-ethanol reforming for hydrogen production, using renewable raw materials and adopting mature and efficient chemical processes, is an important source of green hydrogen supply to achieve the goals of carbon peaking and carbon neutrality. Bio-ethanol is a widely used substitute for fossil fuels. With the continuous progress of cellulosic ethanol technology in recent years, bio-ethanol will gradually break through the constraints of starch-based raw material supply. Based on the industrialization achievements of hydrogen production and bio-ethanol, bio-ethanol reforming can realize a rapid linkage with the existing hydrogen energy industry. However, the existence of a carbon-carbon signal bond in ethanol poses new challenges to the development of hydrogen production catalysts, and production technology for the palladium membrane reactor has been significantly improved, creating an opportunity for the miniaturization of equipment and on-line application of bio-ethanol reforming. Bio-ethanol can be supplied through gas stations, and online hydrogen production can avoid the potential safety hazards of hydrogen storage and transportation. Bio-ethanol reforming for online hydrogen production is expected to achieve a seamless replacement of fuel vehicles in the process of industrialization, which has broad market prospects and great strategic significance. |
