CATALYTIC REACTOR Russian patent published in 1998 - IPC

FIELD: transport engineering; cleaning of exhaust gases in spark ignition internal combustion engines. SUBSTANCE: housing of reactor has coaxially installed porous ceramet oxidation and reduction catalytic units space formed in between, inlet and outlet branch pipes with flanges and end face cover. Auxiliary gas feed channel has outlet in to ring spaces formed between inner surface of housing and outer surfaces of oxidation porous ceramet catalytic units. EFFECT: enhanced cleaning of exhaust gases, reduced amount of toxic matters getting into environment owing to more complete oxidation of products of incomplete combustion in oxidation and reduction stages, reduced heat stress in reactor housing owing to delivery of into oxidation zones. 1 dwg
