Combined systems

In gas engines, and particularly biogas engines, predominantly CO and special catalysts are currently used to reduce toxic formaldehyde emissions to comply with legal requirements. The catalyst substrates contain a catalytically effective high-grade metal coating that is damaged at differing rates by certain components of biogas depending on the coating quality, making it ineffective. The catalyst must then be replaced.

Catalyst poisons include sulphur, phosphorous, zinc, iron, calcium, potassium, manganese, arsenic and sodium.

Exomission biogas catalysts have an especially high-grade, sulphur-resistant coating that increases their service life.

SCR systems are often also required in order to reduce NOx emissions in countries outside Germany due to the stricter emission legislation there – particularly for pilot injection engines operated with biogas.

Various catalysts can be combined with an Exomission SCR system without any problems. We plan according to your individual requirements and deliver the complete system to you, including an easy-to-maintain catalyst exchange substrate system. If you need a replacement for an old or contaminated catalyst, we are also happy to deliver just the substrate with the coating.
