摘要:

糠醛高选择性催化转移加氢制糠醇是生物质高值化利用的重要途径之一,本文以甲酸、乙酸及三氟乙酸为调节剂制备了具有不同缺陷位点的UiO-66,利用XRD、SEM、NH3-TPD、TG和N2吸附脱附等手段进行详细表征,并以异丙醇为溶剂和氢供体,考察了UiO-66催化剂缺陷位、酸性和织构性质对催化糠醛转移加氢反应的影响。结果表明,UiO-66催化剂酸性的增强有利于糠醛转移加氢反应中糠醇选择性的提高,以甲酸为调节剂制备的UiO-66在160℃的反应温度下,反应1h后糠醛的转化率和对糠醇的选择性分别达到99.4%和98.9%。

Abstract:

The highly selective catalytic transfer hydrogenation of furfural to furfuryl alcohol is one of the important routes for high value utilization of biomass. Herein, UiO-66 catalysts with the different defect sites were prepared with formic acid, acetic acid and trifluoroacetic acid as regulators. The catalyst was characterized by XRD, SEM, NH3-TPD, TG and N2 adsorption and desorption. The effects of defects, acidity and textural properties of UiO-66 catalysts on the transfer hydrogenation of furfural were investigated with isopropanol as both solvent and hydrogen donor. The results showed that the enhancement of acidity of UiO-66 catalysts was beneficial to the improvement of furfuryl alcohol selectivity in furfural transfer hydrogenation reaction. The furfural conversion and selectivity to furfuryl alcohol over UiO-66 prepared with formic acid as regulator could reach 99.4% and 98.9% at 160℃ in 1h, respectively.

Key words: UiO-66, biomass, furfuryl, alcohol, catalysis, transfer hydrogenation
