Characterization and Composition of Oil Extracted from Bastard Poom Beans (Sterculia foetida L) and its Potential as a Biofuel
Abstract:
The paper describes an investigation of using oil extracted from Bastard Poom beans as a biofuel. Unlike Palm oil, Bastard Poom bean oil is non-edible, therefore using it as a fuel does not create a demand conflict between food and fuel. Bastard Poom are a type of softwood trees and grown quickly. We find that to obtain a liter of oil, approximately 4.29 kg of beans are needed (oil extraction ratio of 21.57 % by weight). The chemical compositions of oil are determined. The oil consists of 40.16 %. Palmitic acid, 15.67 % Cis-11,14-Eicosadienoic acid and approximately 15 % each of Cis-9-Oleic and Cis-9,12-Linoleic acids. The oil heating value is 39,638 kJ/kg. The viscosity tested at 40 °C and densities tested at 15 °C are 44.61 mm2/s and 929.6 kg/m3, respectively. As a result, it has a considerable potential as an alternative to other biofuels among communities and farmers.
