摘要
木质素经热解或解聚可以获得苯酚、甲氧酚和愈创木酚等木质素衍生酚,木质素衍生酚经过进一步的加氢脱氧(HDO)反应可转化为液体燃料。针对木质素衍生酚HDO反应,首先对比分析了液相和气相条件下的反应机理,总结了反应条件对反应机理的影响。然后综述了贵金属、非贵金属和双金属催化剂的气相HDO反应催化性能。最后指出Fe基贵金属型催化剂在气相HDO反应中表现出良好的发展潜力。
The pyrolysis or depolymerization of lignin can obtain lignin-derived phenols such as phenol,methoxyphenol and guaiacol.These lignin-derived phenols can be converted into liquid fuels after further hydrodeoxygenation(HDO) reaction.Aiming at the HDO reaction of lignin-derived phenols,the reaction mechanisms under liquid phase and vapor phase conditions were compared and analyzed,and the influences of reaction conditions on the reaction mechanisms were summarized firstly.Then the catalytic performances of noble metal,non-precious metal and bimetallic catalysts in vapor phase HDO reaction were reviewed.Finally,it is pointed out that Fe-based noble metal catalysts have good development potential in vapor phase hydrodeoxygenation.
