Nitrogen Isotope Ratio Measurements Apportioning Of Fuel And Thermal Nox: Project Summary

This resource links to a document we hold in our system

Abstract:

The main aim of the project was to develop a nitrogen-stable isotope measurement technique for NOx and to ascertain whether it can be used to determine the relative contributions of fuel and thermal NOx during coal combustion. The specific objectives were to:

  • To design suitable substrates for adsorbing NOx in flue gases.
  • To establish the isotopic values for fuel and thermally-derived NOx with samples from test rigs.
  • To apply the experimental approach to larger facilities and to assess the data obtained for improving existing combustion models.
  • Suitable substrates for adsorbing sufficiently high concentrations of NOx from flue gas streams to facilitate the reliable measurement of the nitrogen stable isotope ratios were developed, the substrates encompassing both manganese oxide supported on zirconia (MnOy-ZrO2) and iron supported on active carbon (Fe/AC).

    This project has established a simple and robust experimental protocol for collecting and determining the stable isotope ratios of NOx from flue gas. The protocol is much more convenient and rapid than that used in the only other reported study where flue gas NOx has been sampled for determining isotopic ratios.
