Abstract
Non-catalytic hydrolysis of soybean oil using subcritical water was statistically optimized in a continuous flow reactor to produce fatty acid (FA). Response surface methodology (RSM) in combination with central composite design (CCD) was applied to evaluate the relationships between the FA content and processing parameters including reaction temperature, pressure, volumetric ratio of water to oil, and reaction time. As a result, both reaction temperature and time had a significant effect on FA content, whereas reaction pressure hardly affected the content of FA. The volumetric ratio had a positive effect on FA content up to a specific level but had a slight negative impact at higher levels. Results showed that optimum processing conditions for maximizing the FA content were 294 oC, 120 bar, a volumetric ratio of 1.8, and a reaction time of 22 min. The predicted FA content was 96.78% under the statistically optimized conditions, and this value was almost identical to the experimental value with an insignificant error of 0.67%.
