Publication: Journal of Environmental Engineering
Volume 144, Issue 11
Abstract
NO and oxidization by in coal-fired flue gas was modeled, and the effects of temperature and concentration on NO and oxidization were investigated. The pathways of NO and oxidization were as follows: and , respectively. There were optimal temperature ranges of NO and oxidization, and the ranges were 650–920 K and 650–750 K, respectively. In the optimal temperature ranges, the conversion rate was greater than 0.9 at , and the conversion rate reached about 0.3 at . oxidization could promote formation to oxidize NO.
