助剂改性Pt/Al<sub>2</sub>O<sub>3</sub>催化剂对丙三醇水重整制氢性能影响

摘要以Al₂O₃为载体，采用浸渍法制备了Pt、Co、Cu、Ni/Al₂O₃ 4种不同活性组分的催化剂（N/Al₂O₃），进一步研究了已制备的催化剂对丙三醇水蒸气重整制氢性能的影响，然后通过添加金属氧化物改变Pt/Al₂O₃催化剂的性能，提高催化剂的活性、稳定性和抗积碳性能，并对催化剂进行了TPR、BET表征。实验结果表明，Pt-Li₂O/Al₂O₃催化剂适用于丙三醇水重整制氢反应，并表现出较好的活性和抗积碳性能。

Abstract： Al₂O₃ was used as carrier to prepare four kinds of catalysts (Pt, Co, Cu, Ni)/Al₂O₃ with different active components were prepared by equal volume partial impregnation method, the effect of prepared catalyst on the hydrogen production performance of glycerol by steam reforming was further studied. Then, by adding metal oxides to change the performance of the Pt/Al₂O₃ catalyst, the activity, stability and carbon deposition resistance of the catalyst are improved, and the catalysts were characterized by TPR and BET. The experimental results show that the Pt-Li₂O/Al₂O₃ catalyst is suitable for the hydrogen reforming of glycerol and has good activity and carbon deposition resistance.
