EFFECT OF THE COMPOSITION OF MODIFIED SO4 2^-/ZrO2 ON CATALYTIC PROPERTIES IN REDUCTION OF NO BY HYDROCARBONS

We have shown that the activity of cobalt-containing catalysts based on sulfated zirconium dioxide in selective catalytic reduction (SCR) of NO by methane depends on the amount of sulfur and the preparation method. Modification of Fe and Mn improves the catalytic behavior of SO4^ 2 -/ZrO2 as a result of the increase in the concentration of active sites.
