Abstract Number: 147 Working Group: Invited by Conference Chair
Abstract Formation of particulate carbon is ubiquitous in many combustion and flame phenomena. Particulate carbon formed in flames or emitted from combustion sources is usually in the form of an aerosol. As a byproduct of combustion, particulate carbon or soot is a major source of air pollutants. Its emission is responsible for a wide range of human health problems. Soot emission is also a major cause of uncertainties in modeling global climate change. On the other hand, particulate carbon has a very long history as a useful material. It found its use prehistorically in cave paintings and provided the black pigment for India ink as early as the Neolithic age. Today, the same versatile material finds myriad uses, from rechargeable batteries as a chemically resistant electrical conductor to fuel cells as a cathode catalyst or catalyst support. This talk aims to provide an overview of the relationship between the properties of carbon particles and conditions of flames in which they are generated. It will provide an in-depth discussion about the reaction mechanism and kinetics of carbon formation in flames.
