In the present study the modeling of the reaction kinetic for direct oxidation of methane to methanol,
using the ferric molybdate catalyst have been discussed. The operating temperature range was 643-
723K and the pressure was 34 bar. The Eley-Rideal based mechanism with surface reaction as rate
determining step has fitted the experimental data well. In this model assumed that at the start of the
reaction adsorbed oxygen, in dissociative form reacts with gaseous methane. The kinetic parameters
(rate constants and adsorption equilibrium constants) are determined by means of Ant Colony
Optimization algorithm (ACO). The selected model parameters were determined and their
correspondence with temperature have been discussed. The reaction rate constants were obtained
from Arrhenius temperature expression and the equilibrium adsorption constants are obeyed from
van't Hoff equilibrium expression.
