摘要/Abstract

摘要： 以浓硫酸为催化剂,采用甲醇-甘油复合溶剂,在高温高压的条件下对竹屑、杨木、桉木和松木进行液化,并且对液化产物进行了中和、过滤和旋转蒸发等一系列分级处理,并对液化固体残渣和气体产物进行分析.主要研究了以竹屑为原料的液化油的分级产物的组成及成分,研究结果表明:竹屑经甲醇-甘油液化,产物经过分级处理得到的主要产物为杂多酚、多糖苷和乙酰丙酸甲酯.多糖苷相主要含有多糖苷和未反应的甘油及其甘油聚合物,其中多糖苷主要为六元环吡喃糖苷,约占41.81%,甘油及其聚合物占47.27%;杂多酚相主要含有乙酰丙酸酯、杂多酚和甘油等化合物,其中甘油及其聚合物占38.04%,杂多酚相物质为难溶于水的焦油相的相对分子质量大的物质,约占杂多酚相的38.41%,并且杂多酚相的相对分子质量主要集中在990左右.

关键词: 生物质液化, 多糖苷, 乙酰丙酸甲酯, 杂多酚

Abstract: Liquefaction of biomass using concentrated sulfuric acid as catalyst and methanol-glycerol complex as solvent was investigated. The liquefied products from bamboo shavings, poplar, eucalyptus and pine were neutralized, filtrated and followed by rotary evaporation. The results show that the product from liquefaction of bamboo shaving are mixture of phenolics and acetyl methyl glucoside. Polyglycoside phase mainly contains about 41.81% of polyglycosides which were mainly pyranoside, and 47.27% of unreacted glycerin and glycerin polymers. On the other hand, polyphenol phase mainly contains levulinate, polyphenols, and glycerol, and the content of glycerine and its polymers is 38.04%. Polyphenols mainly contain phenols and levulinic acid esters, and the average molecular weight of phenolics is approximate 990.

Key words: biomass liquefaction, multi-glucoside, acetyl methyl propionate, polyphenols
