Catalytic exhaust air cleaning in road tunnels
Abstract
The contents of the paper deals with the cleaning of street tunnel exhaust air. Tests have been made in the Plabutschtunnel (Austria) using a catalytic converter for the reduction of the gaseous pollutants CO, NO, NO2 and SO2. The results show a high reduction efficiencyand therefore a reduction of pollutants for several hours. Afterwards the catalytic converter has to be regenerated.
