Abstract

In this paper, we will obtain the analytical approximations solution for a system of two coupled nonlinear differential equations that represent the concentration of ethanol and acetaldehyde by using the Adomian decomposition method combined with the Duan - Rach modified recursion scheme. This system models that determine the kinetic study of ethanol combustion on a $\mathrm{Mn} / \mathrm{Cu}$ catalyst and formulating feasible reaction rate expressions with their corresponding kinetic parameters. The obtain solution have been analyzing that demonstrate the rapid rate of convergence of our sequence of analytic approximate solutions without recourse to comparisons with an alternate solution technique. The Adomian decomposition method yields a rapidly convergent, easily computable and readily verifiable sequence of analytic approximations that are convenient for parametric simulations.
