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#2;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.
