生物油的性质及其分离研究进展
Research progress in the separation and purification of bio-oil
摘要
Abstract
The recent research progress in bio-oil refining is reviewed,including distillation,solvent extraction,chromatography,membrane separation and supercritical extraction.Distillation under ambient or reduced pressure can be used in bio-oil separation,while it suffers from a problem in the thermal sensitivity of bio-oil.On the other hand,molecular distillation is more suitable for the bio-oil refining.Some species can be extracted from bio-oil via solvent extraction,while the major disadvantage of which is the difficulty in the separation of solvent with the extract(s)as well as the low extraction selectivity.Exploring or exploiting peculiar extracting agents with specific functional groups,which can uniquely interact with the desired component in bio-oil,might be an interesting research topic in the future.Chromatography can effectively separate and purify bio-oil,but its low throughput makes it only suitable for high value-added compounds.Supercritical CO_2 extraction is potentially a good way in refining bio-Oil due to its nearby ambient operation temperature.In addition,supercritical CO_2 extraction does not need a process of back-extraction.Fundamental research and integrated technique exploitation for bio-oil refining may be important research topics in the future.关键词
