Title:            Biodiesel production from rubber seed oil using supercritical methanol
Authors:       Ha Tram Huy, Tran Tan Viet, Le Thi Kim Phung
Abstract:     In this work, the objective was biodiesel production from rubber seed oil using SCM in a batch reactor. A non-edible rubber seed oil with high viscosity than diesel contains high FFA and water contents, was used as the feedstock in this study. SCM treatment method is appropriate for this feedstock than the conventional catalyst method. Effects of reaction temperature (240 – 320oC), reaction pressure (78 – 96 bar), reaction time (2 – 50 min), and the solvent to feed ratio (10:1 – 50:1) on methyl esters in the transesterification reaction were examined. As a result, the highest content of methyl esters was 92.7% in 20 min reaction, the reaction temperature of 280oC, the molar ratio methanol to oil of 42:1. In addition, Fourier transform infrared spectroscopy was used as an analytical method to determine methyl esters content of biodiesel in the reaction mixture to monitor the transesterification reaction with a high accuracy. This study demonstrates that SCM treatment method is a feasible process in producing biodiesel from rubber seed oil and the by-product of this reaction (glycerol) is high purity and valuable.
