“…The solubility calculated in both studies is at the same order of magnitude. Moreover, the value of the oil solubility estimated in this present work is of the same order of magnitude as that calculated with the results of Micic et al [31] and presented in part 4.2.4.…”

“…The authors also estimated the solubility of JC oil in SC-CO 2 . Micic et al [31] studied the modelling of SC-CO 2 extraction curves of JC at 323 K and 30 MPa. The curve was modelled using the modified Reverchon-Sesti Osteo model equation.…”

“…From these studies, it appears that the quality of the oil extracted by SC-CO 2 extraction from JC is suitable to biodiesel application. However, it is necessary to emphasize that the study of the SC-CO 2 extraction kinetics has only been investigated in two articles [34,35] and only one study has dealt with the modelling of the extraction curve at 30 MPa, 323 K and a CO 2 flowrate of 3.23 × 10 −3 kg/min [31]. Few studies deal with the solubility of JC oil in SC-CO 2 by taking into account the slope of the first part of the extraction curve [34,35] or by direct experimental measurements [32,37,38].…”

“…The supercritical CO 2 (SC-CO 2 ) extraction method allows a green and rather selective extraction, depending on the operating pressure and temperature, of non-polar compounds, particularly triglycerides that lead to biodiesel after transesterification. These advantages encourage researchers to evaluate the feasibility of SC-CO 2 oil extraction from JC and its use for biodiesel production [27][28][29][30][31][32][33][34][35][36][37]. For the sake of simplicity, the operating conditions of the studies dealing with the SC-CO 2 extraction of oil from JC with pure CO 2 are reported in Table 1.…”

Experimental and modelling investigations of supercritical CO 2 extraction of oil from Jatropha curcas were conducted at a pressure range of 20-40 MPa and a temperature range of 313-333 K at a CO 2 flow rate of 0.4 kg/ h. The extraction yield was estimated to be about 0.6 kg oil /kg biomass for all experiments. The model of broken and intact cells published by Sovová was applied. It was found that the extraction of type B was the most suited extraction type to apply as the experimental extraction curves exhibit three parts. Whatever the pressure and the temperature applied, the asymptotic yield at infinite time was found to be the same. At 20 MPa, increasing the temperature from 313 to 323 K enhances the extraction kinetics. A retrograde solubility zone was found at 30 and 40 MPa. The Jatropha curcas oil solubility in SC-CO 2 was determined and the data were modelled with the Chrastil equation.

“…Most of them used scCO 2 laboratory-scale extraction installation (up to 2 L extraction vessel) to obtain oils from the most popular fruits, vegetables, or herbs, e.g., grapes, olives, and sunflowers (Yang et al 2011;Rai et al 2016;Aladić et al 2015;Milić et al 2015;Duba and Fiori 2015;Del Valle 2015;Da Porto et al 2012a, b), but only a few of them used supercritical CO 2 industry-scale extraction plant to obtain oils, especially from berry seeds .…”

Oily seed extracts were used as research samples in Analytical Laboratory of Raw Materials and Plant Products. Supercritical carbon dioxide extraction on an industrial scale was used to prepare extracts from raw plant materials, usually berry seeds: blackcurrant, raspberry, strawberry, and chokeberry. Gas chromatography analysis was performed on Agilent equipment with single quadrupole mass spectrometer detector and split/splitless injector. Fatty acids (FAs) were determined using indirect method, where they were converted to c o r r e s p o n d i n g m e t h y l e s t e r s ( FA M E s ) d u r i n g trimethylsulfonium hydroxide solution reaction. Comparing the mass spectrum and retention time peak, more than 30 compounds in different oily extracts were qualitatively identified. Quantification of individual fatty acids was based on two different methods. Firstly, it was based on the received peak area, and the results were normalized without correction factor. Secondly, the quantification was based on external calibration curve, for 34 identified fatty acids. The method was validated, and the results, e.g., linearity, precision, limit of detection (LOD), and limit of quantification (LOQ), were presented.
