超临界流体耦合技术的现状及发展

Present situation and development of supercritical fluid coupling technology

超临界流体萃取技术作为一种新兴的分离技术,目前已经得到广泛研究和应用,但也存在不足。本文在对超临界流体萃取技术介绍的基础上,针对其不足,提出了超临界流体萃取技术与其他分离技术进行耦合是发展趋势,并重点对超临界流体萃取技术与膜分离技术、蒸馏技术、色谱技术及结晶技术的耦合做全面阐述。认为超临界流体耦合技术具有广阔发展前景,应重视其研究。

As one of the new isolation techniques, the supercritical fluid extraction technology has already been widely applied and much in research at present, but it has shortcomings. On the basis of the supercfitical fluid extraction technology, the paper points out that the supercritical fluid extraction technology coupling with other separation technology is the developing trend. It gives a focus on comprehensive elaboration for the supereritical fluid coupling with membrane separation, distillation, chromatogram and crystal technology. In the end, it draws a conclusion that the supercritical fluid coupling technology has a wide developing prospect,which should be greatly attached to its research.
