摘要
生物油是生物质经快速热解技术制得的一种液体产品。生物油的特殊理化性质决定其可以进行燃烧,但是必须经过提质才能转化为高品位燃料;此外,生物油物种组成丰富,是重要的化工生产原料。综述了近年来国内外生物油高效利用的技术进展,分别对生物油作液体燃料使用和作化工原料生产化学品的最新研究进行介绍。并分析生物油的品质提升技术——生物油催化加氢和催化裂解的当前研究现状,总结存在的问题,预测了今后的发展方向。最后,展望了生物油未来的发展趋势,并指出生物油高效利用技术具有广阔的发展前景。
Bio-oil is a kind of liquid product manufactured through fast pyrolysis technology of biomass.Based on its specific physical and chemical properties,the bio-oil can be used as a fuel,but it could become high value fuel only by upgrading.In addition,bio-oil can also be used as chemical raw material due to its abundant components.So the technical progress on efficient utilization of bio-oil in recent years was received.The latest research on bio-oil using for liquid fuels and chemical raw materials were also summarized in brief.The advances and related problems of bio-oil upgrading including hydrogenation and catalytic cracking were analyzed along with prediction of development direction for the study.And,the development trend of bio-oil was prospected.It was sure that the technology on efficient utilization of bio-oil had a bright prospect in the future.
