基于Hansen溶度参数的煤直接液化残渣超临界萃取
Supercritical Fluid Extraction of Direct Coal Liquefaction Residue Basing on Hansen Solubility Parameters
摘要
Abstract
The supercritical fluid extraction( SFE) of direct coal liquefaction residue using acetone, isopro-panol and benzene as solvents was investigated. The Hansen solubility parameters were used to clarify the variations of both solvent and the solute in SFE process. An empirical equation in terms of the extended Hansen approach was proposed to correlate the extraction capacity with the Hansen solubility parameters of solvents. The results show that the extraction yield using supercritical benzene, of which the dispersive compo-nent is the major in total solubility parameters, obtained the highest extraction yield. The ideal solubility on organic components in direct coal liquefaction residue improved with the extraction temperature increasing. The empirical equation shows high consistency with experimental results. As a consequence, the theory of Hansen solubility parameter and extended Hansen approach are applicable to the study on supercritical fluid extraction of direct coal liquefaction residue.关键词
