Abstract/OtherAbstract:
|
Animal fat residues (AFR) from waste water were used as feedstock to produce biodiesel by a two-step acid-catalyzed process. Treatment of the AFRs with 5.4% (w/w) of 17M H(2)SO(4) at a methanol/AFR ratio of 13:1 (50%w/w) at 60°C converted more than 95% of the triglycerides into fatty acid methyl esters (FAMEs) with an acid value (AV) of 1.3mg(KOH)/g(biodiesel). Response surface methodology indicated that a lower AV cannot be reached using a one-step acid catalyzed process. Thus a two-step acid catalyzed process was employed using 3.6% catalyst and 30% methanol for 5h for the first step and 1.8% catalyst and 10% methanol for 1h in the second step, resulting in a yield higher than 98% and an AV of 0.3mg(KOH)/g(biodiesel). The product thus conforms to the European norm EN14214 concerning biodiesel. |
