Description

This data presents the experimental results obtained during the execution of selected tasks from the project titled: "Wytwarzanie NOx w atmosferycznej plazmie mikrofalowej – badanie wpływu 'quenchingu' oraz wzbudzenia oscylacyjnego cząsteczek" (English: "NOx formation in an atmospheric pressure microwave plasma – investigating the impact of quenching and vibrational excitation of molecules"), funded by the Polish National Science Centre (NCN), Project No. 2022/47/D/ST8/01512.

The project focuses on the formation of nitrogen oxides (NOx) in atmospheric-pressure microwave plasma.

The presented data includes measurements of nitrogen oxides (NOx), performed using an FTIR analyzer (GASMET), obtained from a microwave plasma reactor under various experimental conditions.


The dataset consist of two files:

1. Nozzle

This set includes results (NO and NO2 cocnentrations) obtained at different flow rates and power inputs tested using compressed air. The results also compares results obtained with and without applying nozzle.

3. Oxygen

A compilation of results for different O2 concentrations using a reactor without a nozzle. This set shows the influence of O2 content on NOx production.


Variables included in the dataset:

Nozzle: Indicates whether the test was carried out in a nozzle reactor (YES) or a non-nozzle reactor (NO).

Flow rate, SLM (standard liters per minute): Volumetric flow rate of air or O₂/N₂ mixture, ranging from 20 to 80 SLM depending on the case.

Power, W: Microwave input power, ranging from 600 to 1800 W depending on the case.

NO_#1, ppm: Nitric oxide concentration (in volumetric ppm). #1 - represent the number of the test

NO2_#1, ppm: Nitrogen dioxide concentration (in volumetric ppm). #1 - represent the number of the test

O2, %: Oxygen content in the O2-N2 mixture.
