摘要
生物质是唯一可转化为液体燃料的、对环境友好的、清洁的可再生资源。通过高压液化或热裂解方法可将生物质制备成类似石油的粘稠状物质——生物油,生物油经过精制可转化为替代石油的常规燃料。生物油的分离与分析具有非常重要的意义,文章综述了生物油的分离与分析技术的研究现状。分离技术包括过滤、萃取、溶解、减压蒸馏;分析技术包括红外光谱、高效液相色谱、气质联用技术、液质联用技术、核磁共振技术等。分析结果表明,生物油含氧量较高,主要含有酸、醛、酮、酚、醚、酯、呋喃等成分。
Biomass is the environment friendly,clean and renewable energy resources which can be transformed into liquid fuel. The liquefaction or pyrolysis of biomass can transform biomass into ropy matter like petroleum. Bio-oil can be refined as fuel to replace the fossil one. The separation and analysis on bio-oil is of great importance. In this paper,the recent status on separation that including filtration, extraction, dissolution, reduced pressure distillation and the analysis technologies such as FTIR, HPLC GC/MS, HPLC/MS, NMR on bio-oil are introduced. The result shows that bio-oil has higher oxygen content, which is composed of acid, aldehyde, ketone, hydroxybenzene, aether, ester, furan and so on.
