FLUE GAS DENTTRIFICATION TECHNOLOGIES AND ANALYSIS OF THEIR CHEMICAL REACTONS[J]. Thermal power generation, 2006, (11): 59-60. DOI: 10.19666/j.rlfd.2006.11.021.
A summary of main chemical reactions for reducing NO
x
with agent NH
3
and corresponding sub-reactions
as well as features
layout
and required temperature range for two main technologies
namely selective non-catalytic reduction(SNCR) and selective catalytic reaction(SCR) have been presented
the composition of catalyst
effect of active components and other components for SCR technology being expounded.It is suggested that the further study on some chemical mechanisms in this catalytic system is also needed.
