- Abstract
- The chemistry of the combustion of simple hydrocarbons to form carbon dioxide and water has been extensively studied and is generally well established. Our level of understanding of the chemistry which leads to the formation of polynuclear aromatic hydrocarbons (PAH) and soot particles is less fully developed. Numerous modelling efforts have been applied to the analysis of concentration data collected in shock tubes and premixed flames. Although there are many proposed routes involving specific hydrocarbon free radicals, these models do share some common features. Fuel molecules are converted to relatively high concentrations of acetylene. Two- carbon atom free radicals formed during this pyrolysis process, or by hydrogen atom reqctions with acetylene, can react with acetylene to form four carbon atom species.
