摘要
生物油是一种可再生的碳中和有机资源,在液体燃料和高值化学品生产中显示出较大的潜力,对其大规模利用有助于实现碳中和目标。生物油因其固有的腐蚀性和化学不稳定性而需要提质以提高其应用价值。电催化加氢能够在常温常压下实现生物油加氢提质,该方法反应条件温和、操作简单、能源效率高,具有碳中和属性,为生物油提质提供了新的选择。综述了近年来生物油电催化加氢的研究进展,分析了不同生物油模型化合物在电催化加氢过程中的作用机理。讨论了真实生物油样品的电催化加氢实例,以证明电催化应用于生物油提质的可行性。最后,针对生物油电催化加氢提质技术面临的困难和挑战,提出了该领域未来的研究方向和重点,并展望了生物油电催化加氢提质工业化应用的前景。
Bio-oil is a renewable carbon-neutral resource that has shown great potential in the production of liquid fuels and value-added chemicals.Large-scale use of bio-oil could help achieve carbon neutrality.Bio-oil requires upgrading to improve its application value because of its inherent corrosion and chemical instability.Electrocatalytic hydrogenation(ECH)can realize the bio-oil hydrogenation under atmosphere temperature and pressure.ECH can be easily controlled by regulating the potential,and have a high energy efficiency.It is a carbon neutral process which provides a new option for bio-oil upgrading.The research progress of ECH of bio-oil in recent years was reviewed,and the mechanisms of different bio-oil model compounds in the ECH process were analyzed.The examples of ECH of real bio-oil samples were also discussed to prove the feasibility of electrocatalytic application in bio-oil upgrading.Finally,in view of the difficulties and challenges faced by ECH of bio-oil,the research direction and focus in this field in the future were proposed.The prospects of industrial application of the electrocatalytic hydrogenation upgrading of bio-oil are prospected.
