To determine the characteristics of simulataneous removal reaction of $SO_x$ and $NO_x$ from flue gas over $CuO/γ-Al_2O_3$ sorbent/catalyst, desulfurization and denitrification reaction of $CuO/γ-Al_2O_3$ sorbent/catalyst have been determined in a thermogravimetric analyzer (TGA) and fixed bed reactor, respectiviely. Optimum operating condition of simultaneous removal reaction of $SO_x/NO_x$ over $CuO/γ-Al_2O_3$ sorbent/catalyst has been determined in a fixed bed reactor.
The sulfation degree of alumina support in terms of the amount of sulfate ions presents on the support can be classified into three types (surface, slightly deep and bulk sulfations) as a function of reaction temperature and CuO loading. Surface sulfation (sulfate ions $<2.0\times10^{18} ions/㎡)$ occurs at CuO loading between 2-11wt% at reaction temperature 250-350℃, slightly deep sulfation $(2.0\times10^{18} ions/㎡
