Oil Extraction from Castor Cake Using EthanolKinetics
In this study, the kinetics and thermodynamics of oil extraction from castor cake using ethanol were investigated. Castor cake had a total oil content of 14.78 ± 0.12% in mass and the average particle diameter was 0.446 mm. Oil extractions were carried out in a stirred batch extractor system at various temperatures (20, 30, 40, and 55 °C).

Kinetics of soybean oil extraction using ethanol as
Similar results were found by Meziane and Kadi (2008) in studying the kinetics of extraction of olive cake oil using azeotropic ethanol as solvent. In this work, the effect of temperature on the kinetics of oil extraction was evaluated from 20 to 50 °C and the authors concluded that increasing the temperature resulted in an increased yield of oil.
