Ionic Mechanisms of Carbon Formation in Flames.
Abstract
The objective of this program is to establish a chemical mechanism of soot formation which will serve as a basis for practical solutions to the smoke problem in jet engines. An experimental program is currently underway at AeroChem to study soot formation in premixed laminar flames to test proposed chemical mechanisms, in particular the hypothesis that soot nucleates on chemically formed ions whose growth is thermochemically favored and proceeds by very rapid ion-molecule reactions. Mass spectrometric measurements of positive ion concentration profiles in rich and sooting acetylene and benzene flames show many similarities and some distinct differences. As sooting is approached by increasing the equivalence ratio, the concentration of large ions with mass greater than 300 grows rapidly. (Author)
