METHOD OF CATALYTIC NEUTRALISATION OF NITROGEN AND CARBON OXIDES IN EXHAUST GASES OF ENGINES, AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC F01N3/00 

FIELD: power industry.

SUBSTANCE: to reaction zone created in catalytic reactor there introduced is fuel up to 0.1% of the main consumption of the engine, and additional reaction of nitrogen oxide neutralisation is carried out. Reaction zone of catalytic reactor is formed between two catalytic surfaces made from high-porous permeable honeycomb material. They are installed with a gap relative to each other. Outlet catalytic surface is provided with additional reducing catalytic agent. Cavity between catalytic surfaces is divided with perpendicular partitions so that there formed between them are local cavities - reaction-reducing zones restricted with inlet and outlet catalytic plates. To the zones there introduced is fuel through micro gas-distributing network and through atomisers which are located on each of the inlet catalytic plates at crossing angles of perpendicular partitions as per the signal of information-control unit depending on signal of measurement channels of nitrogen oxide concentration with infrared sensor of absorption type. Housing of reactor, catalytic plates and additional reaction-reducing catalytic agent are made from magnetic material.

EFFECT: increasing efficiency of neutralisation process of nitrogen oxides owing to possible control of depth of catalytic decomposition level of nitrogen oxides.
