EFFECT OF THE NATURE OF THE OXIDIZING AGENT ON CONVERSION OF FINELY DISPERSED CARBON ON BINARY OXIDE CATALYSTS

We have studied the process of catalytic oxidation of finely dispersed carbon on the surface of the designed soot filters, prepared by successive deposition of a second support (gamma -Al2O3) and a catalytic coating (CuCr2O4 or CuCo2O4) on ceramic honeycomb monoliths of synthetic cordierite, using different oxidizing agents: O2, O3, NO, NO2, H2O. Using ozone as the oxidation initiator allows us to solve the problem of comprehensive purification of automobile exhaust gases at fairly low temperatures (“cold start”).
