在Co/SBA-15催化剂存在下，糠醛加氢制糠醇。报道了在该催化体系上在高于95%的转化率下的高选择性（96%）。研究了还原温度、氢气压力和反应温度对糠醛转化为糠醇的影响。最佳反应条件为：150 ℃，1.5h，2.0MPa的H2-。该催化剂可循环使用，回收的糠醇纯度大于90%。还研究了溶剂浓度的影响。当溶剂含量至少为50wt%时，糠醇的选择性和糠醛的转化率仍然很高（均超过80%）。同样，即使在纯糠醛中也保持了催化剂的活性，这证实了所提出的催化体系的真实的潜力。该催化剂还用于乙酰丙酸加氢选择性生成β-戊内酯。
The hydrogenation of furfural to furfuryl alcohol was performed in the presence of a Co/SBA-15 catalyst. High selectivity (96%) at a conversion higher than 95% is reported over this catalytic system. As the conversion of furfural to furfuryl alcohol occurs over metallic Co sites, the effect of reduction temperature, H-2 pressure, and reaction temperature were studied. Optimum reaction conditions were: 150 degrees C, 1.5h, 2.0MPa of H-2. The catalyst was recyclable, and furfuryl alcohol was recovered with a purity higher than 90%. The effect of the solvent concentration was also studied. With a minimum of 50wt% of solvent, the selectivity to furfuryl alcohol and the conversion of furfural remained high (both over 80%). Likewise, the activity of the catalyst is maintained even in pure furfural, which confirms the real potential of the proposed catalytic system. This catalyst was also used in the hydrogenation of levulinic acid to produce -valerolactone selectively.
