| Title | Efficient conversion of brown grease produced by municipal wastewater treatment plant into biofuel using aluminium chloride hexahydrate under very mild conditions |
| Abstract | Wastes produced by oil/water separation at the wastewater treatment plant of Bari West (Southern Italy) were taken, characterized and converted. About 12% of this material was composed of greases, mainly made of free fatty acids (50%) and soaps (34%), and was easily separable by the aqueous phase through a hot centrifugation. After chemical activation of this fatty fraction, a direct esterification was carried out under very mild conditions (320 K and atmospheric pressure), converting more than 90% of the original free fatty acids into the respective methyl esters in less than 4 h, by using AlCl3 center dot 6H(2)O. The activation energy correlated to the use of this catalyst was also calculated (Ea(est) = 43.9 kJ mol (1)). The very low cost of the biodiesel produced (0.45 (SIC) L (1)) and the associated relevant specific energy (5.02 MJ kg(FAMEs)(-1)) make such a process a really sustainable and effective example of valorization of a waste.
