摘要

生物油是一种由固体生物质热解得到的液体产品，可以作为生产可再生燃料和化学品的可持续原料。以木屑为原料，在锥形喷淋床反应器中快速热解制备生物油。采用液液萃取法，利用极性将生物油分离成不同的化学基团，以稳定生物油，提高生物油的质量。在分离的生物油的水相和溶剂相中存在类似的含氧官能团。以氯仿、己烷和石油醚为原料，采用液-液萃取法从木屑生物油中提取化学物质。溶剂相中有机化合物含量较高。以氯仿为萃取溶剂，水相有机物提取率为65.89%(w)。

Extraction of Value-added Chemicals from Sawdust Bio-oil Through Liquidliquid Extraction

Bio-oil, a liquid product obtained from pyrolysis of solid biomass, can be used as a sustainable feedstock for the production of renewable fuels and chemicals. Sawdust was used as the feedstock for obtaining bio-oil in conical spouted bed reactor through fast pyrolysis. Liquid-liquid extraction method was used to separate the bio-oil into different chemical groups by their polarities to stabilize bio-oil and improve the quality. Similar oxygen-containing functional groups were present in water and solvent phase of the separated bio-oil. Chloroform, hexane, and petroleum ether were used for the extraction of chemicals from the sawdust bio-oil through liquid-liquid extraction. The solvent phase had high concentrations of organic compounds. With chloroform extraction solvent, 65.89%(w) of organics in water phase were extracted.
