摘　　要：介绍了木质纤维素生物质催化转化制取长链烷烃的反应路径。主要从木质纤维素的水解制得平台化合物,中间产物通过羟醛缩合、羟化烷基化、酮化、自身缩合等途径进行加氢脱氧等多步骤合成长链烷烃。阐述了各步转化的反应机理、产物控制途径和相应的催化剂体系,并从技术角度对该领域的研究进行了展望。This paper summarized the multi-step synthetic routes of long chain alkanes from lignocellulosic biomass. Firstly, the key platforms were obtained from the hydrolysis of lignocellulose. Then, the corbon chain growthes of platforms were conducted by aldol condensation, hydroxyalkylation, ketonization, self-coupling, and so on. Finally, the long chain alkanes were obtained from the intermediates by hydrodeoxygenation. The depolymerization of biomass to platforms, the pathways and product distributions depended on platform coupling modes. The hydrodeoxygenation of intermediates to final hydrocarbons was elucidated, The relative solid catalysts in stepwise conversion were also discussed. Finally, the state-of-the-art technologies for biomass derived long chained hydrocarbons were concluded and prospected.
