摘要
在分析生物油特性的基础上,对国内外生物油分离精制技术的研究现状进行了详细分析和评述,包括蒸馏、分级冷凝、溶剂分离、离心分离、色谱分离、膜分离以及超临界萃取分离等,总结了不同分离技术的适应性及存在的问题,指出分级冷凝技术在不改变生物油特性的情况下将能源利用与提取化工产品相结合,经济性较好,具有较好的发展前景,而将膜分离及超临界萃取技术应用到生物油分离中具有很好的研究和开发价值。
Based on the analysis of bio-oil properties, the current status of bio-oil separation and purification technology is summarized, including distillation, fractional condensation, solvent separation, centrifugal separation, chromatography, membrane separation and supercritical extraction. The main problems existing in bio-oil separation are summarized. Investigation trend of the technology is presented. It is suggested that energy utilization and chemical product separation can be integrated through fractional condensation and economical benefits can be maximized. It is also suggested that membrane separation and supercritical extraction have potential research value in the separation of bio-oil.
