Activated Carbon for Dumpgas / Biogas Treatment

The production of biogas is one of the technologies which can be used for the production of renewable energy and therefore is an important part of our energy production in the future.

The methane content of the gas is approx. 60 vol% which is different to natural gas which has a methane content of 85 vol% to 98 vol%. Natural gas contains approx. 11 vol% of inert gases whereas biogas contains approx. 35 vol% of CO2. The moisture content varies in a wide range depending on the materials source. The content of H2S also varies in a wide range.

The demands for the purification of natural gas and biogas are similar. Due to the different composition there are some special requirements for the treatment of biogas.

In order to avoid corrosion in parts of the plant, hydrogen sulphide has to be removed from the gas. The removal also protects catalysts which are used, from an impact by sulphur containing compounds and a subsequent deactivation.
A group of substances which occurs only in biogas are siloxanes. These molecules do not appear in nature but are found in biogases which are produced from municipal waste and wasted fats.

Recommended AC Qualities:
Desorex K 43 J (impregnated) for H2S-removal
Desorex K 47 (untreated) for siloxane separation
