中文摘要	The nickel-based catalysts for aqueous-phase hydrodeoxygenation of furfural were prepared by impregnation method using different supports and characterized by XRD, H(2)-TPR, NH(3)-TPD and low temperature N(2) adsorption The effects of support, nickel loading and reaction temperature on conversion of furfural and selectivity of desired C(5) products were studied. The reaction mechanism of furfural aqueous-phase hydrodeoxygenation and the recyclability of catalysts were also discussed. The results showed that the activities of Ni/SiO(2)-Al(2)O(3) were obviously better than that of the Ni/gamma-Al(2)O(3) under the same reaction conditions. The conversion of furfural over 14wt% Ni/SiO(2)-Al(2)O(3) catalyst was 63% and the selectivity for C(5) was as high as 93% under the optimization condition of 140 degrees C and the cold H(2) pressure of 3.0 MPa. Conversion of furfural increased with increasing temperature, but the selectivity for desired C(5) product decreased with increasing temperature. The conversion of furfural decreased swiftly when the catalyst was re-used for the third time. About 25wt% residual cokes and polymers deposited on the used catalyst surface. 以SiO2-Al2O3、γ-Al2O3为载体采用浸渍法制备了不同负载量的镍基催化剂,以XRD、H2-TPR、NH3-TPD与低温N2吸附等技术对催化剂特性进行了表征,并进行了水相催化糠醛加氢脱氧实验研究以制备以C5为主要成分的生物汽油。重点考察了催化剂的镍负载量、载体种类及反应温度对糠醛转化率、目标产物C5选择性的影响,并对催化剂的重复利用性能和糠醛水相加氢脱氧反应机理进行了探讨。结果表明,Ni/SiO2-Al2O3催化性能明显优于Ni/γ-Al2O3。在140℃、氢冷压3.0 MPa的优化反应条件下,14wt%Ni/SiO2-Al2O3催化糠醛反应的转化率为63%,C5选择性高达93%。升高反应温度可以提高糠醛的转化率,但反应产物的选择性降低。催化剂在第3次重复使用时糠醛的转化率明显降低,催化剂表面有明显的残留有机聚合物和积碳,达到25wt%左右。
