| Abstract: |
| In order to realize the energy utilization of insecticidal fat of black soldier fly larvae(BSFL), biodiesel was synthesized by alkali-catalyzed methyl esterification of insecticidal fat of BSFL extracted with petroleum ether, and on the basis of single factor experiment, the process conditions for the synthesis of biodiesel were optimized by response surface methodology. GC-MS was used to analyze the fatty acid composition of biodiesel. The performance of biodiesel was also evaluated. The results showed that the optimal conditions for the synthesis of biodiesel from insecticidal fat of BSFL were obtained as follows: volume ratio of alcohol to oil 7.2∶1, reaction time 2.0 h, dosage of KOH 1.0% of the total mass of the reaction system. Under these conditions, biodiesel yield reached 93.7%. The main fatty acid composition and content of biodiesel were C12∶0 12.8%, C14∶0 3.8%, C16∶0 16.2%, C16∶1 1.9%, C18∶0 4.4%, C18∶1 24.2%, C18∶2 26.8%, C18∶3 4.1%. The performance of biodiesel were kinematic viscosity (40℃) 3.842 5 mm2/s, kinematic viscosity (25℃) 5.311 mm2/s, dynamic viscosity (25℃) 4.640 mPa·s, density (25℃) 874 kg/m3, density (15℃) 879 kg/m3, acid value 0.12 mgKOH/g, sulfur content 26 mg/kg, open flash point 160℃, closed flash point 142℃, residual carbon less than 0.10%. The biodiesel synthesized from insecticidal fat of BSFL has a high content of C14-C18 and good performance. |
