Application of matlab ordinary differential equation function solver (ode45) in modelling and simulation of batch reaction kinetics

Abstract

This study presents the simulation of modelled chemical reaction in a batch reactor using the Matlab ordinary differential equation function solver (ODE45). Modelling and optimisation of actual batch reaction rate constants under isothermal condition was implemented on a set of experimental data. The data was simulated using hypothetical isothermal rate constants, 1 2 with the initial concentration profile of the reaction: and respectively between reaction time of minutes. The Process model developed was employed to optimise the rate constant (K) at which maximum yield of the desired product was achieved. Results showed maximum product yield, ‘D’ at 1= with a reaction by-product, ‘E’ at 2 = within 40 minutes reaction time. This study is intended to benefit industrial operations which aim at achieving optimum yield of a reaction process in a record time.
