【摘要】 为优化燃料电池氢源,设计了双段固定床制备氢气。利用共沉淀法合成了两组催化剂（NiO/ZnO与CeO₂/ZnO催化剂、Ni/γ-Al₂O₃与Fe₂O₃Al₂O₃催化剂）,研究表明双段固定床可显著提高乙醇水蒸汽重整在中低温条件下制备氢气的选择性,在350℃时分别由原来的56.27%和56.52%上升至58.23%和58.37%。更多还原

【Abstract】 In order to optimize source of fuel cell,double-sector fixed bed was designed to produce hydrogen.Two series of catalysts（NiO/ZnO and CeO₂/ZnO catalysts、Ni/γ-Al₂O₃ and Fe₂O₃/Al₂O₃ catalysts）were synthesized by co-precipitation method.It is found taht double-sector fixed bed could enhance the hydrogen selectivity over ethanol steam reforming in low-intermediate temperature significantly,from 56.27%and 56.52%up to 58.23% and 58.37%respectively at 350℃.更多还原
