摘　　要：商业航空燃料需求的持续增长和世界航空领域的低碳革命促使可持续航空燃料的开发迫在眉睫.木质素具有丰富的芳环结构和高能量密度特征,具有替代化石原料生产航空燃料的潜力,通过加氢脱氧反应将其转化为航空煤油中环烷烃和芳烃组分有助于提高可持续航空燃料的品质.过渡金属硫化物具有良好的抗硫中毒性能和加氢脱氧活性,被视为工业木质素及木质素油升级精炼的理想催化剂,但硫流失、产物污染、水中毒及高温稳定性差等问题限制了其放大应用的潜力.针对这些问题,本文主要总结了本课题组近期在过渡金属硫化物催化木质素定向合成航空燃油环烷烃和芳烃的研究进展,从金属掺杂、边缘工程、基面工程和载体协同等方面,系统地介绍了催化活性、选择性和稳定性的调控策略,提升了催化剂在木质素加氢脱氧反应中的低温活性、防硫流失、抗水中毒、耐高温等方面的能力.最后,结合研究现状讨论了木质素制航空燃料的应用难题和解决策略.The continuous demand growth of commercial aviation fuel and the global low-carbon revolution have driven the development of sustainable aviation fuels an urgent task.Lignin,featuring rich aromatic units and high energy density,has the potential to replace fossil feedstocks for aviation fuel production.Converting lignin into cycloalkane and aromatic components in jet fuel through hydrodeoxygenation(HDO)can enhance the quality of sustainable aviation fuel.Transition metal sulfides(TMS)are considered ideal catalysts for the upgrading and refining of industrial lignin and lignin oil thanks to their excellent sulfur tolerance and HDO activity.However,challenges such as sulfur loss,product contamination,water poisoning,and poor stability at high temperature limit their scalability and application prospects.To address these critical issues,this paper summarizes recent advances in the catalytic conversion of lignin into jet fuel cycloalkanes and aromatics using transition metal sulfides.Particular emphasis is focused on newest strategies,such as metal doping,edge engineering,basal plane engineering,and carrier synergy,for regulating the catalytic activity,selectivity,and stability of TMS in HDO of aromatic monomers,lignin model compounds and lignin oil,thereby enhancing the catalysts’low-temperature activity,sulfur and water resistance,and high-temperature stability.Finally,future trend,challenges and potential solutions from lignin to sustainable aviation fuel are discussed.
