摘要：隨著石油資源的日益缺乏，人們正在加緊尋找石油資源的替代品。生物質(zhì)是石油資源最為潛在的替代物質(zhì)，因?yàn)榻^大部分基于石油的化工原料和產(chǎn)品都可以從生物質(zhì)中提取得到，特別是生物質(zhì)是可持續(xù)能源中唯一芳香基團(tuán)的來(lái)源。目前，大部分的研究集中在構(gòu)成木質(zhì)生物質(zhì)的三種主要成分（纖維素、半纖維素和木質(zhì)素）中較容易轉(zhuǎn)化的纖維素和半纖維素上。相反，利用木質(zhì)素轉(zhuǎn)化為高價(jià)值化學(xué)品的研究尚未引起足夠的重視。木質(zhì)素轉(zhuǎn)化為高價(jià)值化學(xué)品，可解決生物質(zhì)中木質(zhì)素殘?jiān)y以有效利用的難題，從而實(shí)現(xiàn)生物質(zhì)全組分的高效高值化利用。

Abstract：With the growing shortage of fossil fuels， it is stepping up efforts to find alternatives for fossil fuels. Biomass is the most potential alternative substances， because most of the petroleum-based chemical raw materials and products can be produced from biomass. However， most researches have focused on conversion of cellulose and hemicellulose， the relatively easy conversion components of lignocellulosic biomass， remaining lignin under-utilization. With its unique structure and chemical properties， lignin supplies an alternative raw material for the production of high-value phenolics.

Keywords：lignin， clearly separation， biorefinery
