Sorbent technology carbon dioxide sorbents

Previous reports 30, 31) have appeared on the use of siqiercritical fluid extraction (SFE) coupled with siqrercritical fluid fractionation (SFF) for the enrichment of these FPE. Carbon dioxide (CO2) and ethanol (EtOH), as a cosolvent, were utilized to fiactionate and eruich the FPE from 1.2S to 14.5 wt% in com bran oil employing a sorbent bed. However, this prior research was performed on an analytical scale. In the present study, SFF technology of com bran oil has been sc ed up using SFE/supercritical fluid chromatogr hy (SFE/SFC). The oil is remov from the com bran 1 utilizing supercritic carbon dioxide (SC-CO2), and then the extract is fiactionated by on-line SFC to obtain a fraction enriched in FPE.
