The article contains analysis of kinetics of PM oxidation conducted on ceramic SiC bases with oxidizing catalytic layer. Tests were conducted on specially designed and developed prototype stand that enables to conduct experiments in environment similar to conditions in diesel engine exhaust system. Test were conducted in various process parameters: oxidizer temperature, oxygen fraction in the oxidizer and rate of the volumetric flow of oxidizer. A series of experiments were conducted to determine influence of test parameters on the oxidation process. From those experiments temperature characteristic of basic PM oxidation kinetic parameters such as activation energy and oxidation constant were determined.
