中文摘要：

化石资源日益减少和使用化石资源带来的气候与环境问题促使人们将目光转向可再生的生物质资源。由生物质资源制备高附加值的化学品已成为国内外的研究热点。通过催化氢解将纤维素转化为多元醇化学品是一种可行的手段。本文总结了由纤维素氢解制备多元醇的最新研究进展，重点介绍了纤维素转化为山梨醇／甘露醇、异山梨醇和小分子多元醇（丙二醇和乙二醇）的催化剂体系以及可能的转化途径。最后分析了该领域存在的问题和今后的研究趋势。

英文摘要：

Due to climate and environment problems posed by use of fossil resources, developing advanced technologies for sustainable production of value added chemicals from renewable biomass is of scientific and practical importance. Among those, polyols production from cellulose by catalytic hydrogenolysis has attracted more and more attention during the last decade. In this review, we summarized the state-of-art technologies in such area with the aims to the products of sorbitol/mannitol, isosorbide and small molecular polyols （ethylene glycol and propylene glycol）, the employed catalysts and the possible reaction pathways. Finally, we analyzed the 19resent oroblems and the oossible trends in the future.
