Transesterification Oil Chicken Using Different Catalysts

The aim of this study was to evaluate some catalysts in the production of esters from crude chicken and chicken oil pre-treated (neutralized by alkaline solution) oil. The catalysts were evaluated: Amberlyst-15, IR-120 Aberlite, KSF, ZnO, CaO and methanol as the reactant alcohol. The reactions took place starting at 60°C and 80°C, 5 % catalyst relative to the mass of oil, reaction time 5 hours and molar ratio alcohol:Oil 9:1. The catalyst showed the best conversions, approximately 77 % of esters, was calcium oxide (CaO). Then new tests with CaO catalyst were developed. By means of a 23 factorial design were evaluated three important variables in the transesterification reaction temperature, molar ratio alcohol:oil and percentage by weight of catalyst. The highest conversions were obtained of 79.8% and 83% for crude oils and pre-treated, respectively, under the conditions of temperature 90°C, molar ratio alcohol:oil 6:1 and 4 % by weight of the catalyst
