Abstract
The effects of five catalysts on the oxidation rate of ammonium sulfite were compared by intrinsic experiments using self-designed bath reactor. Fe2+ was turned out to be a good catalyst for oxidation of ammonium sulfite. Using stirred bubbling reactor, the kinetics of catalytic oxidation of sulfite in the ammonium-based wet flue gas desulfurization process were investigated by varying concentrations of (NH4)(2)SO4, (NH4)(2)SO3 and Fe2+, pH, air flow rate and temperature. The reaction was found to be first order with respect to ammonium sulfite, 0.4 order with respect to Fe (2+) and the oxidation could reach the maximum rate when pH value was close to 6. The mechanism of the oxidation was discussed and concluded that the oxidation is controlled by diffusion of oxygen.
