摘要
Process for removing nitrogen oxides in waste gases comprises passing the gases at a speed of more than 0.5 m/s through a honeycomb or cell-like catalyst having an open front face of more than 50% with the channels of the catalyst having a hydraulic diameter of more than 2 nm. The novelty is that for purifying waste gas from cement production plants containing more than 5 g/m3 dust, a titanium oxide-containing catalyst is used having a hydraulic diameter of 6.8-30.0 mm and a waste gas speed of more than 3 m/s is used.
