英文摘要	在基于生物质的新能源战略中,多元醇正在成为新一代的能源平台.从纤维素出发,通过热裂解、催化裂化和酸水解加氢等反应能制得多元醇,再以多元醇为原料在较温和的条件下通过水汽重整和费托合成等方法合成燃料、化学品和氢气.本文综述了多元醇经水汽重整制燃料油和化学品或经光解制氢气的进展,介绍了纤维素类生物质资源经催化氢化和水解加氢制多元醇的研究进展.虽然简单地套用现有的工业技术就可以转化纤维素,但这些方法在效率、能耗、规模和环保等方面还存在诸多问题,有效提高纤维素利用率的新思路仍在期待之中.虽然采用精心设计的工艺路线可以有效地转化多元醇,但离“简约、节能、方便可行和环境友好”的要求仍有一定的差距,“一步法”...; In the new energy strategy based on biomass, polyols are becoming a new generation of green energy platform. Polyols can be obtained from biomass by pyrolysis, catalytic pyrolysis, and intercepted dilute acid hydrolysis. They can be converted to biofuels, chemicals, and hydrogen by processes such as aqueous-phase reforming and Fischer-Tropsch synthesis under mild conditions. In this study, pioneer developments on the utilization of polyols to prepare biofuels and chemicals, light-induced decomposition of polyols to hydrogen, and exploring study on the catalytic hydrogenation and intercepted dilute acid hydrolysis of cellulose to polyols have been reviewed. The simple application of current industrial techniques on cellulose conversion is immediately available, whereas the processes in deed are far from high efficiency, low energy cost, large scale, and green. Therefore, new chemistry on one-step conversion of cellulose is being highly expected. The utilization of new concepts combining techniques in a state of the art shows great potentials in the conversion of polyols, but the approaches still keep a long distance from the simplicity, energy efficiency, cheap, and environmentally benign. Hence novel catalysis to realize "one-pot" and "one-step" conversion is also highly expected in the future.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000243503100023&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 12; 12; 1159-1163; 27
