摘　　要：在Ni-B/γ-Al2O3,非晶态合金催化剂中添加Mo改性应用于催化糠醛液相加氢制糠醇反应.采用差示扫描量热法（DSC）、比表面测试（BET）、程序升温还原（TPR）和程序升温脱附（TPD）-系列表征手段,研究催化剂的热稳定性和表面性质,探讨催化剂的活性中心.结果表明,Ni-B/γ-Al2O3非晶态合金催化剂表现出很高的催化活性和对糠醇的选择性.当添加的Mo在催化剂中含量为1.25%～2.5%时,糠醛转化率、糠醇选择性都达到100%.The Mo-modification of the Ni-B/γ-Al2O3 amorphous alloy catalyst for liquid-phase furfural hydrogenation to furfural alcohol is investigated. The thermal stability and the surface properties of the catalysts are characterized by means of DSC, BET, TPR and TPD, respectively. The active center of the catalysts is discussed. The results show that the Ni-B-Mo/γ-Al2O3 amorphous alloy catalyst performances the high activity and selectivity to furfural alcohol. When the quality ratio of Mo to γ-Al2O3 is in the range from 1.25 % to 2.5 %, the conversion of furfural and the selectivity to furfural alcohol for the catalyst are all up to 100%.
