Abstract:

<p>This document is a report for the project titled 'Development of Stable Isotopic Ratio Measurement - Apportioning of Fuel and Thermal NO<sub>x</sub>'.</p> <p>The main aims of the project have been to develop a nitrogen-stable isotope measurement technique for NO<sub>x</sub> and to ascertain whether it can be used to determine the relative contributions of fuel and thermal NO<sub>x</sub> during coal combustion at high temperatures. Suitable substrates for adsorbing sufficiently high concentrations of NO<sub>x</sub> 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, first milestone completed October 2001). </p> This report is divided into the following sections: <ol> <li>Introduction</li> <li>Technical Progress/Overall Planning and Objectives Summary</li> <li>Expenditure</li> <li>Exploitation/Publication of Results</li> </ol> <ul> <li>Appendix 1 - Background nitrogen levels in EA-IRMS for the Europa 20:20 instrument</li> <li>Appendix 2 - Tables</li> <li>Appendix 3 - Details on nitrogen stable isotope measurements obtained using the N-free Fe/Mn-AC</li>
