Formation of NO x from Air and N 2 /O 2 Mixtures Using a Nonthermal Microwave Plasma System
We present an experimental study of NO x (NO and NO 2 ) formation from air and N 2 /O 2 /NO x mixtures using a nonthermal microwave plasma device. The tests were performed considering the energy consumed to generate plasma gas and the flow rate of air. The results demonstrated that NO x production w...

| Summary: | We present an experimental study of NO
x
(NO and NO
2
) formation from air and N
2
/O
2
/NO
x
mixtures using a nonthermal microwave plasma device. The tests were performed considering the energy consumed to generate plasma gas and the flow rate of air. The results demonstrated that NO
x
production was proportional to input power and the inverse of air flow rate. In the experiments that used N
2
and O
2
mixtures instead of air, the maximum NO
x
concentration produced at equilibrium was 16.02 ×10
16
molecules/J (0.66 ×10
16
NO molecules/J and 15.36 ×10
16
NO
2
molecules/J). Under the condition of the source gases consisting of NO and NO
2
of 970 ppm in the N
2
and O
2
mixture with a ratio of 79/21, the concentrations of NO
x
generated were 5,571 and 5,320 ppm. |
