Factorial design and surface method to optimization ethylic biodiesel production from chicken wastes

To produce biodiesel, one of the most important factors is quality oil used in production. However, other such as price and availability should also be taken into consideration. Chicken wastes shows a very promising option for this sector, since it comes from waste. The aim present study was methodology extraction characterization chicken production biodiesel by ethylic transesterification, besides presenting optimization process variables applying RSM involving CCD. investigation performed following evaluation parameters oil: viscosity, density, acidity index, moisture sample, refractive saponification index. For index ester content were evaluated. An optimum point reached where concentration catalyst 2.1% mass, oil/ethanol ratio 1:5.5 reaction temperature 30 ?C; at that point, 95% conversion achieved. At obtained statistical technique p-value 0.05 results found physical- chemical are ANP standards.
