Soot Forming Mechanisms in Combustion Reactions

February 2nd, 1984

Introduction

Earlier works (Ref 1, Appendix A) on the cracking of hydrocarbons and chlorination of hydrocarbons has provided a general mechanism and explicit rate expressions for the formation of carbon which have been found to be consistent with observations in a number of practical cases. The purpose of this note is to consider how the treatment might be extended to combustions where oxygen rather than chlorine is the oxidant and where the temperatures involved are likely to cause cracking.
