Title: EVALUATE THE WASTE FATTY ACID BY SCIENTIFIC AND TECHNICAL STUDY TO OBTAIN BIODIESEL
Author: Barros, AAC
Wust, E
Meier, HF
Abstract: Waste fatty acid, from fatty boxes was evaluated as feedstock to obtain biodiesel in a laboratory scale. The residues were desemulsified, purified and used to obtain ethyl esters, through the transesterification with alkaline catalysis and esterification with acid catalysis reactions. The product was purified by adsorption in column of silica, and characterized by GLC with mass detector. Using this methodology the fatty residues was converted in the ethyl esters showed the scientific e technical validation of this propose. The conversion of fatty acids in ethylic esters was calculated by mass balances processes same for the highs degradation of the residue evaluates. To purify the biodiesel and glycerol obtained was necessary secondary processes to increase the qualities of this full and to use the glycerin in many industrial processes.
