Factorial 24 experiments design to obtain biodiesel from chicken fat using CaO as catalyst

Biodiesel was obtained by transesterification of chicken fat and methanol using CaO from eggshells, through a factorial 2 4 experiment design to evaluate the influence of reaction variables. The fat was characterized through the: refractive index, saponification index, free fatty acids, density, and...

Description
Summary:Biodiesel was obtained by transesterification of chicken fat and methanol using CaO from eggshells, through a factorial 2 4 experiment design to evaluate the influence of reaction variables. The fat was characterized through the: refractive index, saponification index, free fatty acids, density, and viscosity, giving as results 1.465, 183.166 mg KOH g −1 , 1.623%, 0.919 g cm −1 and 63.337 cSt. The temperature was the variable with the greatest impact on biodiesel production. The optimal variables to achieve a viscosity of 5.918 cSt were: temperature 65°C, chicken fat (CF): methanol molar ratio 1:6, catalyst percentage 5% w/w and reaction time of 5 h. Graphical abstract
