Abstract
Biodiesel from non-edible seeds has attracted the attention of the authors to investigate Hevea brasiliensis (HB) and Ricinus communis (RC) as potential feedstocks. Biodiesel production was carried out using esterification-neutralization-transesterification (ENT) process. The transesterification process was carried out under variation methanol to oil molar ratio, catalyst concentration, reaction temperature, reaction time and speed agitation. On top of that, optimization was evaluated using Response Surface Methodology (RSM) and a quadratic polynomial model for ENT method. The optimization results show that production biodiesel from HBME and RCME with ENT method were 99.32% and 99.07% respectively. All the properties measured for produced methyl ester met in ASTMD 6751. Moreover, the presence of ricinoleic (α-elaeostearic) in RCME can improve the cold point, pour point and cold filter plugging point, which resulted in -40.4 °C, -27.8 °C and -35.0 °C respectively. The results of the cold flow properties are better due to higher unsaturated fatty acid concentration. It is indicates that RCME has good performance during cold weather engine operation. It short, biodiesel production using ENT method can produce high methyl ester yield and good biodiesel properties.
