摘 要:介绍了负载型5-羟甲基糠醛(HMF)加氢催化剂的制备方法,对所制备的催化剂进行了N_2吸附-脱附等温线、透射电镜、氢氧滴定、吡啶红外等表征,并采用高压反应釜装置对其催化加氢性能进行了评价。比较了Ru、Rh、Pd、Pt 4种贵金属,MoO_3、WO_3、ReO_3 3种助剂,SiO_2、Al_2O_3、Y型分子筛、S-1分子筛、MCM-41介孔材料5种载体对HMF加氢反应催化剂性能的影响,结果表明,以SiO_2为载体负载Pt及助剂MoO_3制得的催化剂性能较好。HMF呋喃环侧链C—C键和C—O键的断裂是引发后续副反应的重要原因,抑制HMF呋喃环侧链C—C键和C—O键的断裂是提高HMF加氢反应目标产物选择性的关键。Supported catalysts were synthesized for the hydrogenation of 5-hydroxymethylfurfural (HMF).Catalyst preparation methods were introduced,and the obtained catalysts were characterized by multiple methods,such as N 2 adsorption-desorption isotherm,transmission electron microscope,hydrogen and oxygen titration,and Pyridine-adsorbed fourier transform infrared spectroscopy.Catalytic performance of the catalysts was evaluated in a high pressure stirred tank.Effects of four kinds of noble metal (Ru,Rh,Pd,Pt),three kinds of promoter (MoO 3,WO 3,ReO 3) and five kinds of support (SiO 2,Al 2O 3,Y zeolite,S-1 zeolite,MCM-41 mesoporous material) on the performances of catalysts in HMF hydrogenation process were studied.Results show that it is proper to use SiO 2 as the carrier to support Pt and MoO 3 promoter The rupture of C-C and C-O bonds in the side chains of HMF is an important factor to trigger subsequent side reactions.Thus,restraining the rupture favors increasing the selectivity of the target products in HMF hydrogenation reaction.
