In this study, the feasibility of using vegetable oil extracted from tropical crop seed as a biodiesel feedstock was investigated by producing biodiesel and analyzing the quality parameters as a transport fuel. In order to produce biodiesel efficiently, two step reaction processes (pre-treatment and transesterification) were required because the tropical crop oil have a high content of free fatty acids.To determine the suitable acid catalyst for the pre-esterification, three
kinds of acid catalysts were tested and sulfuric acid was identified as the best catalyst. After constructing the experiment matrix based on RSM and analyzing the statistical data, the optimal pre-treatment conditions were determined to be 26.7% of methanol and 0.982% of
sulfuric acid. Trans-esterification experiments of the pre-esterified oil were carried out. As a result, the optimal trans-esterification conditions were 0.8% of KOH and 16.13% of methanol. After trans-esterification of tropical crop oil, the produced biodiesel could meet the major quality standard specifications; 100.8% of FAME, 0.45 mgKOH/g of acid value, 0.00% of water, 0.04% of total glycerol, 4.041 mm2/s of dynamic viscosity at 40 ℃.
