Superior catalysts for selective catalytic reduction of nitric oxide. Quarterly technical progress report, October 1, 1994--December 31, 1994
During the past quarter, progress was made in three tasks. The poisoning effects of alkali metals (as Na{sub 2}O, K{sub 2}0 and Cs{sub 2}O) on iron oxide pillared clay (Fe-Bentonite) catalyst for selective catalytic reduction (SCR) of NO with NH{sub 3} were investigated. The effects of sulfur dioxide and water vapor on the performance of the high activity catalyst, that is, Ce-doped Fe-Bentonite pillared clay (Ce-Fe-Bentonite) were examined. In addition, an iron ion-exchanged titania pillared clay (Ti-PILC) was prepared and its catalytic activity for the SCR of NO with NH{sub 3} was studied, which showed a high activity and a high S0{sub 2} and H{sub 2}0 resistance at high temperatures (i.e., above 400{degree}C).
