Abstract

An experiment was conducted to investigate gas-solid transfer-reaction in flue gas desulfurazation. The dynamic characteristics of pores or pore structure were analyzed for different reactant solid samples having porous property under variant conditions. The experimental measurements indicated that the pore radius and pore specific surface area, pore radius distribution, all were significantly altered as the reaction progressed, which greatly affected or even dominated the dynamic process. The reaction mainly completed in the reactant pores and the alternation of pore structures during the reaction resulted in significant effects on or even dominated the transport-reaction. The pore structure, especially pore distribution, most-probable radius, and peak value of dV/dr, governed the transfer-reaction dynamic process, and the final conversion rate was completely dependent upon the initial porosity of solid reactant
