摘要/Abstract

摘要： 采用浸渍法制备Ni/CaO、Fe/CaO、Ni-Fe/CaO催化剂,用于生物油模化物乙酸水蒸气催化重整反应。对反应前后催化剂进行BET、H₂-TPR、CO₂-TPD、XRD等表征。通过比较3种催化剂重整反应性能得出Ni/CaO催化剂具有最佳性能。进一步研究在Ni/CaO催化剂参与下反应温度、水碳比（S/C）、液时空速（LHSV）等因素对气体组分相对含量变化以及收率的影响。实验结果表明,在反应温度800 ℃、S/C=5、LHSV=1.54 h^-1时,Ni/CaO催化重整反应性能最佳,氢气收率维持在约85%。结合实验数据和反应前后催化剂表征可知,Ni/CaO催化剂能有效抑制催化剂表面积炭的形成,助剂Fe的添加可提高Ni与Ca-Fe载氧化的相互作用,促进CO的转化。

Abstract: Ni/CaO, Fe/CaO and Ni-Fe/CaO catalysts were prepared by impregnation method. The catalysts were characterized by BET, H₂-TPR, CO₂-TPD, XRD. By comparing the reforming reactions of different catalysts, it is concluded that Ni/CaO has the best performance. The effects of reaction temperature, steam to carbon S/C, liquid-hour air velocity （LHSV） and other factors on the relative content of gas components and hydrogen yield were studied with the participation of Ni/CaO catalysts. The experimental results show that Ni/CaO catalytic reforming has the best performance when the reaction temperature is 800 ℃, S/C=5 and LHSV=1.54h^-1, and the yield of hydrogen was maintained at about 85%. Through the analysis of the experimental results and the catalyst characterization results, it can be seen that the Ni/CaO catalyst can effectively inhibit the formation of carbon deposition on the catalyst surface, and the addition of Fe can improve the interaction between Ni and Ca-Fe oxygen carriers and then promote the conversion of CO.
