摘要：开发了一种新的生物质热解油精制方法。通过将生物质热解油加水预分离,得到水溶性组分和非水溶性组分分别加以利用。水溶性组分通过反应精馏的方法得到混合酯类化合物,收率21%(以生物原油计算)。非水溶性组分可以有两种方式进行加工利用:1)替代苯酚合成热塑性酚醛树脂,通过DSC性能分析,所合成的树脂满足常规树脂的应用要求;2)通过相转移催化法合成高品位液体燃料油,通过GC-MS分析,非水溶性组分中的羧基和酚羟基转化为相应的酯和醚类化合物,降低了生物油的酸性、提高了稳定性。
A novel procedure of refining biomass-pyrolysis oil was developed. The procedure was based on fractionation of the bio-oil with water into water-soluble and water-insoluble fractions. Water-soluble fraction was used to obtain ester mixture through reactive rectification. The yield of ester mixture was about 21% （based on original bio-oil）. According to its molecular structure, two methods were provided to utilize water-insoluble fraction（ mixture of phenolic compounds） as follows： 1 ）Water-insoluble fraction was used as a substitute for phenol at different ratio to prepare phenolic novolac resins. The obtained resin possessed suitable curing time and softening point as conventional novolac resins. 2） Upgraded bio-oil was obtained by Williamson reaction using phase transfer catalysis. The result of GC-MS analysis showed that carboxylic and phenolic groups in the water-insoluble fraction were transformed into corresponding esters and ethers while acidity was lowered and stability was improved.
