Abstract

Biodiesel is an alternative fuel produced from renewable vegetable oils, animal fats or recycled cooking oils by transeste1ification reaction. Biodiesel has drawn significant attention due to increasing environmental concern and diminishing petroleum reserves. However, using edible oils to produce biodiesel is not encouraged because it is competing resources with the food industry. Therefore, a possible solution to this issue is to produce biodiesel from non-edible oils such as Hevea Brasiliensis seeds. Production of Hevea Brasiliensis involve cultivation, oil extraction and transesteritication. In conventional oil extraction, mechanical pressing is used. But, the residual oil left in the oil cake may be anywhere from 6% to 14% by mechanical pressing. The solvent extraction method recovers almost all the oils behind only 0.5% to 0.7% residual oil in the raw material. Due to the increasing demand and investment on Hevea Brasiliensis production. Thus, solvent extraction seems to be more economical tor large scale production. N-hexane and water mixtures will be the solvent for the extraction. Using nhexane will give advantages since it can cut down the processing cost. However, due to the limited data on solvent extraction, the thennodynamics properties such as solidliquid equilib1ium data, distribution coefficient, and enthalpy change and entropy change is studied. Therefore, this study will suppm1s the production of biodiesel li·mn Hevea Brasiliensis oil by using solvent extraction with n-hexane as the solvent.
