An. Pestryakov et Va. Ametov, FOAMED-METAL-BASED CATALYTIC AFTERBURNERS IN AUTOMOTIVE EXHAUST SYSTEMS, Russian journal of applied chemistry, 67(2), 1994, pp. 275-277
Properties of exhaust afterburning catalysts based on porous cellular
materials (foamed metals) have been investigated. Catalysts containing
oxides of base metals provide a two-to-threefold reduction of CO emis
sion. Platinum-containing foamed catalysts lower the toxicity of exhau
st by 85-90%. A favorable effect is demonstrated by the combined use o
f afterburners and a motor oil additive based on ultradispersed copper
.
