摘　　要：生物质转化为高价值呋喃平台化合物是生物质资源利用的重要方式。以工业副产物偏钛酸作为固体酸催化剂,将茭白秆转化为5-羟甲基糠醛(HMF)和糠醛,研究物理活化、溶剂体系等对茭白秆水解性能的影响,并优化反应工艺条件。结果表明,茭白秆具有更低的木质素含量和纤维素晶型结构,比茭白叶更容易被物理活化。在200℃、30 min的反应条件下,球磨活化的茭白秆获得了最高的HMF和糠醛收率,分别为11.66%和7.30%。反应动力学分析表明,偏钛酸催化球磨茭白秆转化的活化能低,相较于文献报道的其他木质纤维素生物质,球磨茭白秆的高值化转化具有优势。The conversion of biomass into high-value furan platform compounds is an important way of biomass resources utilization.In the present study,the industrial by-product metatitanic acid was used as a solid acid catalyst for the conversion of water bamboo(Zizania latifolia)stem to 5-hydroxymethylfurfural(HMF)and furfural.The effects of physical activation and solvent system on the hydrolysis performance of water bamboo stem were investigated and the reaction process conditions were optimised.The results showed that,due to the lower lignin content and the crystal structure of cellulose,water bamboo stem could be more easily physically activated than the water bamboo leaf.Under reaction conditions of 200℃and 30 min,the activated water bamboo stem after ball milling obtained the highest yields of HMF and furfural,which were 11.66%and 7.30%,respectively.The reaction kinetics analysis showed that the activation energy of the water bamboo stem after ball milling catalysed by metatitanic acid was low,which exhibited advantages compared to other lignocellulosic biomass reported in literatures.
