Granular activated carbon coal quality test methods for desulfurization and denitrification
Part 5. denitration rate
1 Scope
This section GB/T 30202 specifies the desulfurization and denitrification granular activated carbon from coal (hereinafter referred to as activated coke) ability to remove nitrogen oxides
The measurement principle, measurement procedures and the results of calculation content.
This section applies to the determination of activated coke NOx removal rate.
2 Principle of Measurement
Containing nitrogen oxides, mixed gas of ammonia, oxygen, nitrogen and water vapor through a bed of activated coke, gas is nitrogen oxide
Ammonia selective catalytic reduction (SCR) of nitrogen emissions. When the SCR reactor reached steady state, the volume fraction of NOx conversion with pass
The ratio of the gas volume fraction of nitrogen oxides is active coke denitration rate.
4NO 4NH3 O → 2 4N2 6H2O
2NO2 4NH3 O → 2 3N2 6H2O
3 Reagents and materials
3.1 nitrogen concentration of 99.5%.
3.2 Nitric oxide, formulated with an inert gas, the volume fraction of not less than 5%.
3.3 oxygen, 99%.
3.4 ammonia concentration of not less than 5%.
3.5 Water, GB/T 6682, three water.
4 instruments and equipment
4.1 denitration rate measurement test apparatus (see Figure 1), consists of the following main components.
a) flow meters, dividing the value of 0.1L/min;
b) water metering pump, 0 ~ 50mL/min;
c) ceramic ring with a diameter of 6mm ~ 8mm;
