چکیده انگلیسی
This study investigated microwave extraction approach to extract lipids from the black soldier ï¬y larval containing high lipids for biodiesel production. The comparison of the effects of different factors (solvent types, extraction temperature, and solute-solvent ratio) on the kinetics and thermodynamic of lipids extraction from the energy insect was investigated in detail. A mathematical model of lipids extraction from the pretreatment insect powder was proposed. The solid-solvent ratio and temperature can have a pronounced effect on lipids extraction rate k. The final yield of lipids increased by a factor of about 1.0-1.04 for extraction temperature elevated by 10 °C. The diffusion of lipids in the solvent constituted the limitation step in the process of extraction. The magnitudes of the diffusion coefficients range from 6.7 Ã 10â12-16.1 Ã 10â12 m2/s for three solvents used. The values of the activation energy Ea were 84.26 kJ molâ1 during the diffusion stage (30 °C-60 °C). At last, the three thermodynamic parameters results (ÎH, ÎS, ÎG) were also obtained from the extraction process.
