- The influence of sulfate on the selective catalytic reduction of NOx on the Ag/Al2O3 catalyst was
studied when CH4 was used as a reducing agent. Various preparation methods influenced differently on the deNOx
activity. Among the methods, cogelation precipitation gave best activity. When sulfates were formed on the surfaces
of samples prepared by impregnated and deposition precipitation, deNOx activity was enhanced as long as
suitable forming condition is satisfied. The major sulfate formed in Ag/Al2O3 catalyst was the aluminum sulfate
and it seems that this sulfate acted as a promoter. When Mg was added to the Ag/Al2O3 catalyst it promoted deNOx
activity at high temperature. Intentionally added sulfate also enhanced deNOx activity, when their amount was
confined less than 3 wt%.
