Structural and functional design of catalytic converters for emissions from internal combustion engines

Abstract

We consider some features of technology for manufacturing advanced three-way (CO/NO x /C n H m ) catalytic converters for emissions of internal combustion engines, namely, application, stabilization, and modification of γ-Al2O3 second supports on synthetic cordierite matrices and Pt, Pd, and Rh active components, as well as oxidation of finely divided carbon on the surface of soot filters coated with a catalyst coating in the form of binary oxide compositions (CuCr2O4 and CuCo2O4) using a number of oxidizers (O2, O3, NO, NO2, H2O, and CO2).
