可再生生物质资源的能源化利用能有效缓解能源短缺和环境恶化的双重压力。木质纤维素类生物质原料通过催化转化途径可以转化成为用途广泛的平台化合物,如呋喃类化合物、多元醇和有机酸及其酯类衍生物等。以这些平台化合物为原料,通过基元反应的转化可以制备高附加值的生物质基液体燃料。基于上述背景,本文概述了国内外木质纤维素通过不同催化转化途径制备各种新能源平台化合物的研究进展。目前木质纤维素制备新能源平台化合物的可行途径主要包括液体酸催化、固体酸催化、离子液体催化和多功能材料催化。在介绍这些催化途径的同时,重点讨论了所使用的催化剂,分析了仍然存在的问题和可能的解决措施,同时对今后该领域的研究前景进行了展望。 |

With the shortage of fossil fuels and the concerns related to their environmental impact and greenhouse gas effect,extensive research and development programs have been initiated worldwide to convert biomass into valuable products for future biofuels and chemicals. The conversion of lignocellulose into platform chemicals has attracted more attention in recent years. During this process,cellulose and hemicellulose can be high selectively converted into soluble sugars in the presence of catalysts,and the soluble sugars are subsequently converted into widely used platform molecules,such as furan-based chemicals,polyols,organic acid and its ester derivatives. These platform molecules can be further refined into high value-added liquid hydrocarbon fuels through elementary reactions,which are important alternatives to fossil fuel. The catalysts used for the transformation of lignocellulose into various platform chemicals mainly include liquid acid, solid acid, ion liquid and multifunctional materials,which play an important role in the catalytic process. Based on the present research situation,this review provides new insights into the accomplishments in recent years in the chemocatalytic technologies to generate energy platform chemicals from lignocellulosic biomass,with an emphasis on various kinds of catalytic routes and their existing problems and possible solutions. Finally,the future research and development trend in the field is prospected. |
