Abstract:

In fires, the concentrations of soot and carbon monoxide are found to be strongly correlated and a significant fraction of the CO emitted from fires is believed to originate from soot particle oxidation. There have been a number of studies of particle oxidation within flames and in shock tubes, but little work on post-flame oxidation. We recently initiated a study of the transformation of post-flame smoke with an emphasis on the chemical transformation of surface-adsorbed polynuclear aromatic hydrocarbons and the subsequent formation of gas phase molecular oxidation products.
