| Résumé : |
The present high price for biodiesel results from the high prices of it’s main feedstock—soybean (USA) and canola oil (Europe). The potential profit from the utilization of low cost tannery fat wastes for biodiesel production depends on the processing costs of the pre-treatment technology; which includes their refining and esterification of free fatty acids. A suitable ratio of tetramethylammonium hydroxide, which is used as an alkali esterification agent of free fatty acids and simultaneously as a transesterification catalyst, enables making biodiesel production from tannery waste feedstock economically profitable. Optimization of the pre-treatment technology is presented using a proposed mathematical model. The final biodiesel properties can be improved by its production from the blends of the waste fats with waste oils. |
