Experimental investigation on transfer-reaction characteristics in porous media
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
