Simulation and Optimization of Biodiesel Production by Soybean Oil Transesterification in Non-Ideal Continuous Stirred-Tank Reactor

Abstract

This research examines the transesterification reaction of soybean oil with methanol in order to model and simulate a non-ideal continuous stirred-tank reactor. A mathematical model has been developed for the reactor. The biodiesel production process was optimized by application of factorial design 25 and response surface methodology. Factorial design and response surface analysis were combined with modeling and simulation to determine the operating conditions that maximize biodiesel production and minimize reactor volume. The optimum results obtained were conversion (0.95), molar ratio alcohol/oil (6:1), temperature (60.5 oC), ? (0.75), bypass (0.10) and reactor volume (1,500 L).

Optimization of biodiesel production from waste cooking oil using ion exchange resins

“…Subsequently, the conversion hardly increased by increasing in catalyst amount from 4.5g to 6g and such behavior is consistent with the previous work [4]. This trend can be ascribed to the fact that there would be an excess catalyst sites for reactants after certain amount of catalyst and thus the reaction rate remains constant beyond the optimum point [5]. It can be concluded that the reaction achieved an equilibrium which is not alerted by the increase in catalyst dose thereafter.…”

“…Giovantilon F. et al [5] examined the transesterification reaction of soybean oil with methanol in order to model and simulate a non-ideal continuous stirred-tank reactor. A mathematical model was developed for the reactor, and the process optimization has been done using factorial design 2 5 and response surface methodology.…”

Development of Bio-Jet Fuel Production Using Palm Kernel Oil and Ethanol

“…8 indicated that ethyl esters increased when ethanol concentration increase. Moreover, greater ethyl esters conversion with high molar rario of ethnol in longer time, which similar to [19]. Vice versa, Tanaka et al reported that the esters conversion achieved at high values at shorter time of reaction, this due to the using of methanol [20].…”

Dry Above Ground Biomass for a Soybean Crop Using an Empirical Model in Greece

“…In this study we tried to present a simple model using geostatistical methods in a simple form. A similar approach is the responsive surface methodology (RSM), which has been used by researchers as an optimization technique with a wide range of applications, such as in dehydration operations of selected agricultural crops [1] and for biodiesel production [2][3][4][5][6]. Also, in the optimization of tomato yield [7], to increase resistant starch in vermicelli [8] and optimization of the plough working surface [9].…”
