Property catalytic reduction method (SCR), three-way catalyst method (TWC), the hydrogen auxiliary method such as lean operation.Selective catalytic reduction
(SCR) denitration is at certain temperature and catalyst action, to make reducing agent using ammonia or hydrocarbon and be optionally reduced to NOx
The method of nitrogen and water.The removal efficiency of NOx up to more than 90% can be made.Influence of this method to atmosphere quality is current less
Denitration efficiency is the most ripe, and most widely used denitration technology.But secondary pollution caused due to the control error of ammonia amount etc.
Reason causes generally to be only capable of reaching 65%~80% clean-up effect；Three-way catalyst method (TWC) be by the effect of catalyst,
CO, HC, NOX are aoxidized respectively, the carbon dioxide (CO2), nitrogen (N2) and the vapor that are harmful to human health is reduced to
(H2O), in conversion process, catalyst can play catalytic purification, three-way catalyst to tri- kinds of nuisances of CO, HC, NOx simultaneously
Method (TWC) can be effectively reduced the discharge of NOx, but spend relatively costly simultaneously, and economic benefit is relatively low.
