Isomer-Resolved Probing of Complex Systems of Reactions

Nils Hansen Sandia National Laboratory

This talk summarizes our recent advances towards a detailed understanding of the low- and high-temperature chemistry of combustion through experiments using idealized laboratory-scale model flames and jet-stirred reactors. Specifically, the talk will highlight four distinct aspects of our work: (a) Aromatics formation in hydrocarbon flames with a focus on the significance of various pathways to form aromatics, especially larger polycyclic aromatic hydrocarbons (PAHs). (b) The investigation of two-dimensional temperature field around a quartz sampling probe using X-ray fluorescence spectroscopy and the impact of combustion chemistry modeling. (c) The detection, identification, and quantification of elusive, peroxided intermediates during the low-temperature oxidation processes through an integrated experimental and theoretical approach. (d) The development and exploration of new experimental capabilities that can be applied for chemically detailed studies of the formation of PAHs and highly oxygenated intermediates.
