Abstract

Furfuryl alcohol (FA), a valuable compound from furfural (FF) was synthesized by efficient Ni-Cu/ZrO₂ catalysts. The catalysts with varying Ni and Cu loading were developed by sol-gel method and characterized by Brunauer-Emmet-Teller (BET) method, X-ray diffraction, Temperature Programmed Reduction (TPR), X-ray photoelectron spectroscopy techniques. Cu/ZrO₂ and Ni/ZrO₂ catalysts were also tested to compare the effect of the Ni-Cu/ZrO₂ catalyst. Both Ni and Cu showed the synergistic effect on FA formation. The Ni-Cu/ZrO₂ catalyst was used for hydrogenation of FF by changing pressure, catalyst loading, temperature and time. A 93% FA yield was achieved over the 7Ni-Cu/ZrO₂ catalyst with 0.07 g Ni and 0.1 g Cu/1 g ZrO₂ at 200 °C for 4 h under 1.5 MPa H₂ pressure. The sol-gel Ni-Cu/ZrO₂ catalyst without the use of expensive noble metals is effective on the hydrogenation of FF to FA relatively in mildly reaction pressure.

高效溶胶-凝胶镍-铜/氧化锆催化剂上糠醛加氢制糠醇

摘要

糠醇（FA）是糠醛（FF）的一种有价值的化合物，是通过高效的Ni-Cu / ZrO ₂催化剂合成的。通过溶胶-凝胶法开发了具有不同Ni和Cu负载量的催化剂，并通过Brunauer-Emmet-Teller（BET）方法，X射线衍射，程序升温还原（TPR），X射线光电子能谱技术对其进行了表征。还测试了Cu / ZrO ₂和Ni / ZrO ₂催化剂以比较Ni-Cu / ZrO ₂催化剂的效果。Ni和Cu均显示出对FA形成的协同作用。通过改变压力，催化剂负载量，温度和时间，将Ni-Cu / ZrO ₂催化剂用于FF的氢化。在7Ni-Cu / ZrO _2上实现了93％的FA收率在200℃和1.5 MPa H ₂压力下，用0.07 g Ni和0.1 g Cu / 1 g ZrO ₂制备催化剂4小时。不使用昂贵的贵金属的溶胶-凝胶Ni-Cu / ZrO ₂催化剂相对在适度的反应压力下可有效地将FF氢化为FA。
