Most automobiles are currently supplied with a three-way catalytic converter (TWC) for the simultaneous removal of major pollutants CO, NO_X and HC.

Dry carbon particulate aggregated on three-dimensional structure of nickel-foam material of trap. The process of soot tapping is continuous when a filter is included in an exhaust assembly, but here soot destruction and reduction NOx is also continuos at temperatures in excess of 300 ⁰C.

Catalytic blocks based on HPCM has specific  surface 10-100 m2/g, content of precious metals is 0.1-0.5 mass % from general mass of a block,  working temperature for oxidation  of CO is 120-800  0 C, for reduction of nitric oxides is 250-500 0 C.

The catalytic combustion was carried out in air, at temperatures between 200 and 500 ⁰C
