中文摘要：

化石资源的日益枯竭,能源需求的不断增长以及全球气候和环境的不断恶化,迫使人类不得不寻找能替代化石资源的可再生新能源.近年来,生物质能由于广泛易得、廉价、碳中性等特点获得了世界各国的高度重视并得到飞速发展.以生物质及其衍生物为原料,催化转化制备多元醇更是成为当前国内外化学工作者的研究热点.多元醇作为一种重要的工业原料,可用于合成氢气、液体燃料和化学品.作为自然界最为丰富的生物质,纤维素可以通过催化转化的方法转变为多元醇.本文对纤维素制备山梨醇、异山梨醇、乙二醇、丙二醇的研究进展进行了总结和评述,并结合本课题组的一系列工作提出了纤维素制备多元醇的未来挑战.

英文摘要：

Because of decreasing crude-oil reserves, and increasing concerns regarding global climate change and higher energy demands, focus has recently turned to the exploration of new renewable alternatives to fossil feedstocks for the production of energy fuels and chemicals. Recently, biomass has attracted much attention and been rapidly developed because it is readily available, cheap, and carbon neutral. In particular, the catalytic production of polyols from biomass and its derived compounds has become the subject of global research. Polyols, which are important industrial raw materials, are widely used for the production of hydrogen, liquid fuels, and chemicals. Cellulose, the most abundant source of biomass in nature, can be catalytically converted to polyols. This review summarizes and comments on recent advances in cellulose upgrading for the production of polyols（sorbitol, isosorbide, ethylene glycol, and 1,2-propylene glycol）; it also outlines the challenges in this field, and our research work.
