This paper deals with a lumped model for methanol conversion to olefins (MTO process) at atmospheric
pressure and over a temperature range of 673-773 K. The kinetic scheme used in this work for the MTO
process groups the components into lumps and is based on that proposed for MTG process by Schipper and
Krambeck (1986). In this paper applicability of the computational fluid dynamics (CFD) simulation for
catalytic conversion in fixed bed reactors has been shown and details of the CFD models and reaction model
are explained in the following. The simulations were carried out in an isothermal reactor with feeds of
methanol and water in different mass ratios. Methanol was used as feedstock and water was used for
attenuating the coke formation.
