Faraday Symposia of the Chemical Society, 1973
Probable mechanisms are discussed of the formation processes of pyrolytic carbon films and soot particles, based on experimental investigations of their formation rates. Both are two-stage processes including nucleation and growth of nuclei. The formation of pyrolytic carbon from methane at temperatures below 1300 K is a molecular process.

1993
In this chapter topics relevant to soot formation during combustion are given, as well as the results of recent research centered around these. Sooting in flames has long been studied not only from scientific viewpoint but also for practical purposes, such as promotion of radiative heat transfer in boilers and furnaces and reduction of soot emitted as ...

Polymer Degradation and Stability, 1990
Abstract Soot formed during the combustion of polymers is actually produced from the gas phase resulting from thermal decomposition of the polymer. The mechanisms of soot formation from gases are described. The description includes (i) the formation of soot precursors and soot particle inception, (ii) the aggregation of particles, (iii) the surface ...

Modelling Soot Formation: Model of Particle Formation
2013This article reports on detailed models of soot particle formation in combustion. First, we present the polycyclic aromatic hydrocarbon-primary particle (PAH-PP) model where soot particles are described by primary particles which are made up of PAHs.

Model of Soot Formation: Coupling of Turbulence and Soot Chemistry
1994The aim of our study is to model soot formation in the extreme conditions of Diesel engines. The first concept has been to use a formulation for soot formation deduced from the most recent experimental work. However, in order to take into account the effects of turbulence and pressure, associated to soot production, we had to use very simplified ...

Formation of soot can take place in all kinds of practical combustion systems, especially in systems which operate on a diffusion flame concept. The influence of macroscopic system parameters on the amount of soot formed is rather well investigated for different systems.

Under ideal conditions the combustion of hydrocarbons leads to mainly carbon dioxide and water. Ideal conditions may be specified by stoichiometric composition of the combustible mixture, i.e. the oxygen content of the mixture everywhere is sufficient to convert the fuel completely according to the formal chemical equation $$ C_m H_n + \left( {m + \

Formation of Hydrocarbons and Soot
1996Hydrocarbons and soot predate NO x (Chapter 17) as pollutants from combustion. In earlier times, smoke from the factory smokestack was a sign of prosperity. In time it became a nuisance and finally a health concern. The remedy to the appearance of soot and smoke are the three “t’s” of combustion: time, temperature, and turbulence (Babcock and Wilcox ...

A mechanism for the formation of soot particles and soot deposits
Combustion and Flame, 1992The extent of the role of polycyclic aromatic hydrocarbon (PAH) species in the mechanism of soot formation has not definitely been determined. In previous work using a flat-flame, water-cooled, premixed burner burning ethylene-air flames we investigated the formation and destruction of PAH species up to five aromatic ring structures.

Metal enhanced soot and PAH formation
Combustion and Flame, 1993Abstract Iron and manganese have been added to laminar, sooting, premixed ethylene/oxygen/nitrogen flames with fuel equivalence ratios ranging from 2.22 to 2.49. The iron concentration was 200 ppm in the fuel, while the manganese concentration was 140 ppm in the fuel (mole basis). The additives increased the amount of soot formed under all conditions,
