Separation and Utilization of Classification Products in Liquefied Oil of Biomass
摘要
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.关键词
