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。生物質是石油資源最為潛在的替代物質,因為絕大部分基于石油的化工原料和產品都可以從生物質中提取得到,特別是生物質是可持續能源中唯一芳香基團的來源。目前,大部分的研究集中在構成木質生物質的三種主要成分(纖維素、半纖維素和木質素)中較容易轉化的纖維素和半纖維素上。相反,利用木質素轉化為高價值化學品的研究尚未引起足夠的重視。木質素轉化為高價值化學品,可解決生物質中木質素殘渣難以有效利用的難題,從而實現生物質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
