Catalytic Reduction of Flue Gas NOx

Nitrogen oxides (NOx) are major air pollutants generally arising from combustion processes. Removal of NOx from stationary and transportation power sources is an important process in meeting increasingly stringent environmental regulations. Currently, most methods in use rely on the use of ammonia (NH3), which adds system complexity to account for the toxic nature of ammonia as well as to prevent fouling due to side reactions. The use of hydrocarbons for the reduction of NOx is a desirable process from a system design point of view; however, most systems using hydrocarbons as reducing agent are not able to operate under oxygen rich, or lean burn, conditions. Researchers at the University of British Columbia have designed a novel method and apparatus for the hydrocarbon selective catalytic reduction (HC-SCR) of NOx in flue gas emissions that is compatible with oxygen rich combustion processes. Advantages:
•
Method works under lean burn conditions
•
Combustion fuel can be used as reducing agent
•
Eliminates use of harmful ammonia
