Abstract:

This study investigates the effect of preparation strategies on the state of active species in Beta zeolite supported P and Ni catalysts,to develop high⁃performance catalysts for the selective hydrogenation of furfural.A series of P⁃modified Beta zeolite supported Ni catalysts were prepared by stepwise introduction of Ni and P through different methods.Various characterization techniques were employed to investigate the state of Ni species,and their catalytic performance in the selective hydrogenation of furfural was evaluated.The results revealed that Ni species introduced via the in⁃situ hydrothermal method were uniformly encapsulated within the zeolite channels.P introduced via mechanical mixing migrated into the channels and interacted with Ni to form Ni2P species during reduction treatment.The high content of Ni2+ in P⁃Ni@Beta indicated a strong metal⁃support interaction.The reaction results demonstrated a blue shift in the C-O stretching frequency,indicating electron transfer from Ni to P,which reduced the electron density around Ni.The reaction results indicated that Ni δ+ species,acting as Lewis acid sites,efficiently promoted the selective hydrogenation of furfural.Under conditions of 110 ℃ and 1 MPa H2,a furfuryl alcohol yield of 68.6% was achieved after 1 h of reaction.

Key words: Beta zeolite, Metal Ni catalyst, Preparation method, Hydrogenation of furfural

摘要:

探究了制备方法对Beta沸石负载磷镍催化剂中活性组分存在状态的影响,进而开发了高效的糠醛选择性加氢催化剂。首先,通过不同方法在Beta沸石上逐步引入Ni和P,制备了Beta沸石负载磷镍催化剂;然后,利用多种手段表征了各催化剂中活性金属Ni组分的存在状态;最后,评价了各催化剂的糠醛选择性加氢反应性能。结果表明,原位水热法引入的Ni物种均匀分布在沸石孔道中,通过机械混合法引入的P在还原过程中进入孔道与Ni作用形成了Ni2P物种;P⁃Ni@Beta中Ni2+的相对含量高,表明其具有较强的金属⁃载体相互作用;P⁃Ni@Beta催化剂中,C-O拉伸频率发生蓝移,表明Ni与P之间的电子相互作用会降低Ni周围的外电子密度;P⁃Ni@Beta催化剂中,Ni δ+作为L酸中心可以高效催化糠醛选择性加氢反应,在温度为110 ℃、H2压力为1 MPa的条件下反应1 h,可获得68.6%的糠醇收率。
