Selective catalytic reduction of nitrogen oxides by ammonia (DeNOx)
Testing catalytic activity for selective catalytic reduction of nitrogen oxides with ammonia is carried out in a flow reactor under isothermal conditions at atmospheric pressure. The percentage of nitric oxide (II) conversion is taken as a measure of catalytic activity.
Testing of fixed-bed catalyst activity is performed for fraction from 1.0 to 3.0 mm. Catalyst performance is tested according to approved test methods.
The acquired data enable to determine the loading and optimal process conditions for catalyst commercial application.
Advantages
Applying state-of the-art highly sensitive IR-Fourier spectrometer equipped with a thermostatically controlled flow cell with a variable optical path (2.1-10.6 m) allows quantitative analysis of component concentrations in gas streams with an accuracy of up to several ppm.
Testing time – 5 hours.
Option of customized testing according to unstandardized test procedure agreed with the customer).
