超临界CO_2萃取再生活性炭技术研究进展

Progress on Regeneration of Activated Carbon by Supercritical Carbon Dioxide Extraction

超临界流体由于密度大、粘度低、表面张力小,是再生活性炭的理想溶剂。文章介绍了超临界CO_2萃取再生活性炭的原理、研究现状、设备和工艺流程及对该工艺的影响因素,表明了该技术在活性炭再生上的特点、优势及应用前景。

Because of its high density, low viscosity and low-surface tension, supercritical fluid can regenerate spent activated carbon. Through reviewing the regeneration principle, equipment, process and affecting factors of supercritical fluid extraction technology, its characters, advantages and application were presented.
