Oxidation Kinetics of Magnesium Sulfite in Presence of Synthesized Solid Catalyst

Abstract:

In the present paper, a bubbling reactor is employed to investigate the macroscopical kinetics of magnesium sulfite oxidation in presence of the solid catalysts. A synthesized solid metal catalyst M was selected by performance comparison, which had significant catalytic effect on the oxidation rate of magnesium sulfite. The experimental results indicated that the reaction orders are 0 and 0.61 with respect to magnesium sulfite concentration and oxygen partial pressure. Moreover the apparent activation energy of the reaction is 10.66 KJ/mol. Thus a useful reference is provided for recycle of byproduct by catalyzed oxidation in magnesia desulphurization.
