Abstract

The present research reports on an optimized pilot project for plant and the production of BIODIESEL through alkaline-catalyzed transesterification of waste cooking oil. The reaction variables used were methanol/oil molar ratio (3:1-9:1), potassium hydroxide catalyst (concentration 0.25-1.50%), and temperature (45-65°C), and mixing intensity (200-600 rpm). The interaction of these factors on BIODIESEL conversion was ignored. An evaluation of the transesterification process was followed by gas chromatographic analysis of the cooking oil fatty acid methyl esters (BIODIESEL) at different reaction times. A factorial experiment in the form of complete randomized design was employed as the analysis method. A study of the factors affecting the BIODIESEL purity shows that, within the experimental range considered, all exert positive effect on the BIODIESEL purity with the BIODIESEL purity increasing when the values of these variables increase. The BIODIESEL with best purity and quality was produced at methanol/oil molar ratio of 6:1; potassium hydroxide catalyst concentration of 1.0%; mixing intensity, of 600 rpm and reaction temperature of 65°C. The yield of the BIODIESEL produced under optimal conditions was 94-95%. As a result of this study, maximum conversion of free fatty acids esterification (95%) was obtained within 2 hours. Finally, changing the performance of the operating units, the constructed plant output was twice that of such a similar plant as BDI-80.
