Soot Precursor Particles in Flames
1994Thermophoretic sampling was conducted in buoyancy dominated diffusion flames fueled by ethene, methane and acetylene and in the laminar ethene flame. Small polydisperse singlet particles which are more transparent to the electron beam are found at intermediate temperatures on the fuel side of the flame front in these flames.

Effect of Oxidation Catalysts on Diesel Soot Particles
Environmental Science & Technology, 2006The effect of a conventional oxidation catalyst and a novel particle oxidation catalyst (POC) on diesel particles is studied using identical methodology. Regulated particulate matter emission measurement is followed by analyzing soluble organic fraction.

Aromatic site description of soot particles
Combustion and Flame, 2008Abstract A new, advanced soot particle model is developed that describes soot particles by their aromatic structure, including functional site descriptions and a detailed surface chemistry mechanism. A methodology is presented for the description of polyaromatic hydrocarbon (PAH) structures by their functional sites.

Soot Particle Nucleation and Agglomeration
1983In considering the overall phenomenon of soot formation, we are dealing with the evolution of a carbonaceous aerosol in hot reactive gases. If we assume that this aerosol is well described as a monodispersion of spherical particles, its characterization can be made with a knowledge of the particle number density N, the diameter of the particles d, and ...

Electrophoretic Aerosol focusing for Soot Particle Analysis
2015In this work, a focused deposition technique was developed and applied to soot particles produced in a laminar premixed flame of ethylene and air. Particles were collected by means of an Electrostatic Precipitator (ESP), coupled with a Corona charger device used for unipolar charging of particles.

On the Effective Density of Soot Particles in Premixed Ethylene Flames
Combustion and Flame, 2018In this work, the effective density of soot particles was studied in burner-stabilized-stagnation premixed ethylene flames, at an equivalent ratio of 2.0 and over the maximum flame temperature of 1747 ...

Chemical Kinetics of Soot Particle Growth
Annual Review of Physical Chemistry, 1985The light given off by a candle flame and the black smoke from wood burning fireplaces, diesel engines, and industrial furnaces have a common origin: tiny carbonaceous soot particles. The light of a candle comes from incandescent soot particles that ultimately burn up in the air at the top of the flame.

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.

Combustion and Flame, 1991
Although there have been many studies of soot formation, the processes involved are still not fully understood. Recently, particular attention has been directed at the rate of growth of soot particles when rich premixed hydrocarbon-oxygen mixtures are burned in a flat flame, but an alternative approach is to compare the reported growth rates for soot ...
