Reaction Process Study on Flue Gas Desulfurizafion with Pyrolusite Pulp

Flue Gas Desulfurization(FGD) with pyrolusite pulp utilizes the mixture that is made up by pyrolusite pulp and water as an efficient desulfurization agent.It can not only solve the problem of SO_2 pollution,but also produce MnSO_4 used in industry and result some economic benefit.In this paper,the stirring speed,the temperature,the concentration of SO_2 in solution,the grain size of pyrolusite and the concentration of solid are studied.We calculate the energy of activation if the reaction,conclude that the process is controlled by the double membrane,apply mathematics model to describe the react process,establish kinetics model of reaction between SO_2 and pyrolusite.It provides the basis about kinetic theory,and lays the solid foundation for the application of this FGD technology in industry.
