DEVICE FOR REDUCING EMISSION OF DIBENZODIOXINE, DIBENZOFURAN AND SOLID PARTICLES Russian patent published in 2010 - IPC F01N3/10 

FIELD: chemistry.

SUBSTANCE: device for reducing emission of polychlorinated dibenzodioxines and polychlorinated dibenzofurans formed on at least one catalyst which contains transition metals, where the said catalyst is deposited on a solid particle filter fitted in the exhaust pipe of an internal combustion engine, and cannot be removed from the said line without breaking down the structure. In order to reduce emissions, between the catalyst, which contains transition metals, and spent gases on the side of the gases to undergo cleaning, there is at least one molecular sieve which traps polychlorinated dibenzodioxines and polychlorinated dibenzofurans. The molecular sieve on the side of the incoming stream and/or said device, before the molecular sieve, has oxidation activity towards hydrocarbons, polychlorinated dibenzodioxides and polychlorinated dibenzofurans.

EFFECT: reduced emissions of olychlorinated dibenzodioxides, polychlorinated dibenzofurans, solid particles and NO_x.
