Oxidation catalysts

Oxidation catalysts convert hazardous compounds like CO, VOC (volatile organic compounds), formaldehyde and other hydrocarbons to the nontoxic products CO2 and H2O. Precious metals like platinum and palladium are used as active components along with special promoters and binders which are added to maximize catalytic activity and durability. Oxides with very high surface area are used to support the precious metals and together, these materials are coated onto ceramic or metallic substrates.

In contrast to the total oxidation other applications require a selective oxidation, e.g. of nitrogen containing organic compounds where nitrogen oxides are not supposed to be formed. This is realised by using precious metal free oxidation catalysts. Apart from a high activity and selectivity, INTERKAT catalysts provide a long lifetime and stability regarding thermal aging, poisoning and deactivation by ash which is formed due to the combustion of oil and lubricants. Based on these features INTERKAT technologies are capable to cover numerous applications like the exhaust treatment of CHP (combined heat and power) plants, roasteries, greenhouses, automotive and therefore account to a cleaner environment.
