SCR (selective catalytic reaction) exhaust gas aftertreatment systems are used for exhaust gas purification in gas engines and ignition jet engines that run on biogas, natural gas, sewage gas, landfill- or mine gas, as well as in diesel engines. By adding a reducing agent (AdBlue), the nitrogen oxides (NOx) are selectively converted to nitrogen (N2) and water (H2O). With the aid of an SCR dosing system, the reducing agent is fed from a tank to the injector and dosed in the direction of a mixing device in order to achieve an ideal mixing of ammonia with the exhaust gas flow in the exhaust gas system. At the same time, the SCR catalyst selectively converts formaldehyde. A downstream barrier catalyst additionally converts carbon monoxide and prevents the emission of ammonia.
The basis of SCR catalysts is very thin, high-temperature stable foils made of heat-resistant alloys, which are given a honeycomb-like structure by a special winding. For safe nitrogen oxide reduction and formaldehyde conversion, the wound metal foils are coated with a special and very resistant coating.
SCR catalysts from Emission Partner are designed for high conversion efficiency of nitrogen oxides and formaldehyde, and for long-term stability.
All of our SCR catalysts are manufactured 100% in our own production facilities and we guarantee that your emission limits will be safely met and that the emission measurement will be successfully passed.*

n the far west of the republic on the Lower Rhine, only a few kilometres from the Dutch border, one of the first biogas plants that Envitec built for Karl Josef Heimes in 2003 is located in Kerken.
