AB  - Tehnološki postupak dobijanja metil-estara masnih kiselina iz suncokretovog ulja u prisustvu sirovog biodizela kao kosolventa i CaO kao katalizatora testiran je na laboratorijskom nivou. Istraživanje je urađeno radi validacije tehnološkog procesa, određivanja prinosa i sastava MEMK, kao i mogućnosti ponovnog korišćenja izdvojenog katalizatora u reakciji, bez ikakvog dodatnog tretmana prečišćavanja ili kalcnacije. Definisan tehnološki postupak je šaržnog tipa i obuhvata sedam faza jednog ciklusa: aktivacija katalizatora, metanoliza suncokretovog ulja, izdvajanje katalizatora centrifugiranjem, uparivanje metil-estarske faze (tj. sirovog biodizela) i sušenje biodizela.

AB  - Crude biodiesel was proven as a cosolvent in the methanolysis of sunflower oil catalyzed by calcined CaO. This reaction was modeled and optimized statistically in terms of reaction temperature (33.2–66.8 °C), methanol-to-oil molar ratio (3.5:1–8.5:1) and catalyst concentration (0.219–1.065 mol/L). The cosolvent loading was 10 wt% (based on oil weight). The optimum reaction conditions were found to be: the methanol-to-oil molar ratio of 7.1:1, the catalyst concentration of 0.74 mol/L and the reaction temperature 52 °C, ensuring the best esters content of 99.8%, for the reaction time of 1.5 h, which is close to the reported experimental value of 98.9%. Also, the used catalyst was recycled with no additional treatment in the further four consecutive cycles under the following reaction conditions: methanol-to-oil molar ratio 6:1, the concentration of catalyst 0.642 mol/L (only in the first run), the reaction temperature 50 °C, cosolvent-crude biodiesel loading 10 wt% to oil weight. The second recycling reaction provided the highest FAME content of 97.7% after 5 h.
