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
degrees C), alpha (0.75), bypass (0.10) and reactor volume (1,500 L).
