超临界流体萃取分离渣油及超临界流体的选择与应用

Investigation for Supercritical Fluid Destraction Residue and the Selection of Supercritical Fluid and Application

研究应用大型超临界流体萃取精密分离装置，采用iC04、nC05作为超临界流体，分离三种减压渣油。通过实验数据分析与讨论及与工业应用比较， nC05作为分离与评价渣油的超临界流体接近工业生产实际。

This theis applies the large-scale supercritical destraction unit. It is used to seperate threekinds of residues byiC4 and nC5, as the supercritical fluid The study points out that nC,5 supercritical fluid isvery sutable for residue seperation and evalution through comparing experimental data with data of industry processing unit.
