| 摘 要： | 采用微波辅助条件下热解稀硫酸预处理的麦秆制取生物油,产物采用分级萃取进行固液分离,依次分离出了环己烷萃取物、乙酸乙酯萃取物、甲醇萃取物和四氢呋喃萃取物,并用气相色谱/质谱联用仪（GC/MS）分析了各级萃取物。结果表明,本研究制取的生物油中化合物种类较少,有利于生物油中高附加值化学品的分离,其中5,6-二氢吡喃-2-酮在环己烷萃取物中的相对含量为45.0%,糠醛在生物油总产物中的相对含量为45.6%。此外,生物油中酸的相对含量为16.0%,表明该生物油含酸量高而不易于直接作为燃料油使用。

| Abstract: | In this study,wheat stalk was pretreated using dilute sulphuric acid and then pyrolyzed under microwave irradiation to produce bio-oil.The products were extracted with cyclohexane,ethyl acetate,methanol and tetrahydrofuran sequentially,and the extraction solutions were analyzed with GC/ MS.The results showed that only a small number of bio-oil components existed,so it easy to separate the high added-value chemicals from the bio-oil.The relative content of 5,6-dihydropyran-2-one in the extractive by cyclohexane was 45.0%,and the relative content of furfural in all of the bio-oil was 45.6%.In addition,the relative content of acids in the bio-oil was 16.0 %,which demonstrated that the bio-oil cannot be used as fuel oil directly due to its high acid content. |
