Abstract

This study evaluated the extraction process of transformer grade oil from coconut seed waste using a soxhlet extractor in a batch process. The thermodynamic and kinetic properties of the process were evaluated while a comparison was drawn for the experimental and predicted yields at temperatures of 80, 75, and 70 oC. The mass transfer model gave good fit with the experimental data with R2 values above 0.99. The extraction process performed at 80 oC had the highest R2 value and the least error and 𝝌𝝌𝝌𝝌𝟐𝟐𝟐𝟐, values while the model best describes the process at this temperature. Effective diffusivities (Deff) were obtained as 𝟐𝟐𝟐𝟐.𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔 × 𝟏𝟏𝟏𝟏𝟏𝟏𝟏𝟏-𝟑𝟑𝟑𝟑𝒄𝒄𝒄𝒄𝒄𝒄𝒄𝒄𝟐𝟐𝟐𝟐-𝒔𝒔𝒔𝒔-𝟏𝟏𝟏𝟏 , 𝟐𝟐𝟐𝟐.𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔 × 𝟏𝟏𝟏𝟏𝟏𝟏𝟏𝟏-𝟑𝟑𝟑𝟑𝒄𝒄𝒄𝒄𝒄𝒄𝒄𝒄𝟐𝟐𝟐𝟐-𝒔𝒔𝒔𝒔-𝟏𝟏𝟏𝟏 , and 𝟐𝟐𝟐𝟐.𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔𝟔 × 𝟏𝟏𝟏𝟏𝟏𝟏𝟏𝟏-𝟑𝟑𝟑𝟑𝒄𝒄𝒄𝒄𝒄𝒄𝒄𝒄𝟐𝟐𝟐𝟐-𝒔𝒔𝒔𝒔-𝟏𝟏𝟏𝟏 at temperatures of 80, 75, and 70 oC respectively. Enthalpy (Δ𝑯𝑯𝑯𝑯𝒐𝒐𝒐𝒐) of 34.82 Jmol-1 indicates the endothermic nature of the extraction process and the energy requirement whereas entropy (Δ𝑺𝑺𝑺𝑺𝒐𝒐𝒐𝒐) of 104.09 Jmol-1K describes the process as irreversible.
