Biodiesel fuel is a renewable fuel for diesel engine consisting of fatty acid methyl ester from organic oils and fats. In the conventional processes for production biodiesel fuel, glycerol is generally produced as a by-product. But, utilization of this by-product for other application is very hard, since various impurities are mixed. Therefore, we developed new process that does not generate glycerol. This process is simultaneous process of non-catalytic transesterification and thermal decomposition as treated in supercritical methanol. The product treated with 450°C in reaction temperature, 40MPa in pressure and 4 minutes in time is almost same properties with traditional biodiesel fuel. |
