Abstract

The advantages and the properties of biodiesel over the petroleum diesel with its conventional process are outlined. A novel process base on catalytic reactive distillation method with presence of metal oxides as heterogeneous catalyst is proposed to improve the performance of conventional method. Since bio-oil has poor volatility, high viscosity, coking and corrosiveness characteristic, it is suggested to upgrade the bio-oil. Biodiesel is one of the types for upgraded bio-oil that can be used as a green fuel. Esters from bio-oil can he converted into hiodiesel through esterfication I trans-esterification process by mixing hio-oil and alcohol together with presence of catalyst. Conversion, yield and selectivity of hiodiesel from hio-oil using reactive distillation approach are investigated. Selected reaction parameters were optimized, using Taguchi L9 Orthogonal Array method for design of experiments, to yield the lowest free fatty acid content in the tina! product. The investigated parameters include alcohol to hio-oil ratio, temperature and amount of catalyst. The etlect and significance of each parameter were then studied and verified by additional experiments .. Optimum conditions for the reaction were established and effect of each variable was investigated. The optimum conditions tor base transesteritication which could reduce the tree fatty acid content in the feedstock were at temperature of 90"C with butanol/bio-oil ratio of 3: I and CaO at 2wt% (reactant basis). The conversion of butyl ester (hiodiesel) was completed atier I 0 minutes with yield of 65.35% and the product quality was compared to the conventional petroleum diesel. Besides. conversion and yield produced between solid base catalyst (CaO) and acid catalyst (lhS04) were also compared.
