Novel method for determination of kinetic constants from dynamics in a batch reactor with constant heat input rate

Sunil Kumar Thamida, Ameer Khan Patan

Abstract


In this article a novel method of obtaining reaction kinetic constants is described. It consists of measuring both concentration and temperature dynamics in a batch reactor supplied with a constant heat input rate. A system of esterification reaction between acetic acid and methanol in the presence of a cationic resin catalyst is studied. This reversible reaction’s rate is modeled by molecular order and as pseudo homogeneous assumption. By just one experiment it is shown possible that the kinetic constants such as frequency factor and activation energy for both forward and backward reactions by the use of multi parameter optimization technique such that the predicted concentration dynamics matches the experimental data successfully. It is useful for scale up of reactors from lab-scale to industrial scale. Keywords: Reaction kinetics; esterification; catalysis; pseudo homogenous model; optimization
