CO2/NOx-Process

Method for catalytic removal of CO2 and NOx from waste gas

WO 2013/072257 A1

Typical waste gas inlet parameters:

NOx content up to 1 vol.%
CO2 content up to 30 vol.%
Temperature up to 80°C, inlet reactor

Typical clean gas outlet parameters:

NOx content ≤200 mg/Nm³
CO2 content 0 vol. %


The raw gas travels through an activated carbon catalyst fixed bed reactor. Adsorption of NOx or formation of N2 is observed together with production of carbonaceous products, e.g. fertilizer.


The by-products may be further used.
