Özet
Reaction kinetic of magnesite with SO2 gas has been studied in aqueous medium. The effect of particle size, flow rate of the gas, temperature, solid-liquid ratio and stirring speed on the fractional dissolution of magnesite has been determined. The fractional dissolution is found to be inversly proportional to changes in particle size and solid-liquid ratio and, directly proportional to changes in the temperature, flow rate of the gas and stirring speed. The results obtained from experiments are interpreted by the use of solid-fluid heterogeneous kinetic models. It has been found that, the dissolution rate of magnesite is controlled by the surface reaction. The activation energy for the reaction is calculated to be 81 kJ/mol. -from English summary
