在Ni/纳米Al_2O_3催化剂上对苯酚、醋酸和羟丙酮三种典型的生物油模型化合物进行了催化重整反应。选择了长度约为40 nm的纳米棒形式的氧化铝作为催化剂载体。该催化剂在活性和稳定性方面表现出了优异的性能。在700℃反应温度下，苯酚、乙酸和羟丙酮的转化率分别达到84.2%、98.2%和98.7%，相应的氢产率分别为69%、87%和97.2%。该催化剂在三种模型化合物的催化重整反应中保持了10h以上的高活性。考察了水炭比、催化剂负载量和催化剂中镍含量对重整反应性能的影响。此外，还提出了苯酚、乙酸和羟丙酮的可能分解途径。版权所有(C)2014，氢能源出版有限责任公司。爱思唯尔有限公司出版。保留所有权利。
Catalytic reforming of three typical bio-oil model compounds, phenol, acetic acid and hydroxyacetone, has been carried out over a Ni/nano-Al2O3 catalyst. Al2O3, in the form of nano-rods of length approximately 40 nm, was selected as the catalyst support. The catalyst showed superior performance in terms of activity and stability. The conversions for phenol, acetic acid and hydroxyacetone reached 84.2%, 98.2% and 98.7%, respectively, at the reaction temperature of 700 degrees C. The corresponding hydrogen yields were 69%, 87% and 97.2%. The catalyst maintained its high reactivity for more than 10 h in the catalytic reforming of three model compounds. The influences of steam to carbon ratio, catalyst loading and Ni content in the catalyst on the reforming performance were also investigated. In addition, the possible decomposition pathways for phenol, acetic acid and hydroxyacetone are proposed. Copyright (C) 2014, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
