This study investigated the kinetics of the sorption reaction for gaseous lead capture in the packed bed of cal-cined kaolin at 973-1,173 K. The effects of bed temperature and gaseous reactant concentration on the sorption reaction rate were observed by the analysis of experimental data with a developed kinetic model. Detailed information on the lead-sorbent reaction were obtained by the XRD(X-ray diffraction) pattern analysis and the microscopic analysis of pre- and post-sorption sorbent samples. The reaction between metakaolinite, which is the calcination product of kaolin minerals, and the gas-phase lead generated stable metal-mineral complexes(PbAl2Si2O8). An increase in bed temperature resulted in an increase of captur-ing rate, but it had no effect on maximum uptake. The order of sorption reaction with respect to the lead concentration, m, was determined to be 1.67. The activation energy, E a , was estimated as 10.16 kcal/mol, according to the Arrhenius relationship.
