Study on the Effects of Factors on Prickly Ash by Supercritical CO2 Extraction

Abstract:

The aim of this manuscript was to investigated the effects of process paraments on the extracted rate of the prickly ash by supercritical-CO2 fluid.Those parameters include extracting pressure,time,temperature,inventory rating,and dosage.The optimum process parameters were determined by single factor and orthogonal experiment and listed as follows: pressure 33-35 MPa,temperature 50 ℃,time 3.5 h,CO2 flow rate 15-25 L/h,entrainer dosage 15%.
