燃料电池氢源——双段固定床优化乙醇重整制氢

HYDROGEN SOURCE FOR FUEL CELL-OPTIMIZATION OF ETHANOL REFORMING FOR HYDROGEN PRODUCTION THROUGH DOUBLE-SECTOR FIXED BED

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Fe2O3/Al2O3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%.

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 that 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 ℃.
