| Popis: | The aim of this study is to investigate the effect of particle sizes on yield, diffusivity, mass transfer and morphological characterization on extraction rate of rubber seed oil recovery by supercritical carbon dioxide (ScCO2). Pressure 30 MPa, temperature 60 oC and average particle size 500 µm gives the maximum oil recovery (34.71%), diffusivity coefficient (5.13 E-12 m2/s) and extraction rate (0.6 mg/sec). The morphological characterization of extracted rubber seeds was done on the basis of scanning electron microscopy which was parallel with the results of the effect of particle size. The results obtained from gas chromatography-mass spectrometry showed that the rubber seeds oil contained significant essential fatty acids and certain chemical constituents which are very valuable. |
