| Abstract | 采用浸渍法制备了Ni/γ-Al2O3，Ni/HZSM-5和Ni/KZSM-5 3种负载型催化剂，利用XRD，XPS，BET，NH3-TPD，CO2-TPD和H2-TPR等手段对催化剂的晶相、比表面积、酸/碱性等物化特性进行了表征，并通过固定床反应器对比考察了不同载体的Ni基负载型催化剂对乙醇水蒸气重整制氢的催化性能。实验结果表明：由于HZSM-5的酸性较强，Ni/HZSM-5催化剂不能有效催化乙醇水蒸气重整制氢，主要产物为乙烯；由于KZSM-5具有一定的碱性并有较高的比表面积，Ni/KZSM-5催化剂对乙醇水蒸气重整制氢表现出了较高的催化活性，当反应温度为450℃时，乙醇转化率为100%，氢气选择性达到65.0%，且反应积碳率仅为3.0%；由于载体的碱性较弱，导致产物中含有部分乙烯，降低了氢气选择性，从而Ni/γ-Al2O3催化剂的活性低于Ni/KZSM-5催化剂。 |
| Other Abstract | Ni/γ-Al2O3, Ni/HZSM-5 and Ni/KZSM-5 catalysts were prepared by impregnation method, and tested by XRD, XPS, BET, NH3-TPD, CO2-TPD and H2-TPR, for examine the characteristics of crystal phase, specific surface area, acidity and basicity. Bio-ethanol steam reforming was carried out in a fixed-bed reactor to analyze the catalytic performance of Ni/KZSM-5, Ni/HZSM-5 and Ni/γ-Al2O3 catalysts. It was found that Ni/HZSM-5 showed little activity for bio-ethanol steam reforming, with ethene as the main product due to the strong acidity of HZSM-5; Ni/KZSM-5 exhibited relative high activity for bio-ethanol steam reforming with ethanol conversion of 100%, high hydrogen selectivity of 65.0%, and low carbon deposition rate of 3.0% at 450 ℃; Ni/γ-Al2O3 exhibited lower activity for ethanol steam reforming because some amount of ethene was produced as well. |
