Large molecules, ions, radicals, and small soot particles in fuel-rich hydrocarbon flames

Autor: K.-H. Homann, A.B. Fialkov

Publikováno v: Combustion and Flame. 127:2076-2090

Previous studies of large hydrocarbons in fuel-rich hydrocarbon flames have shown that the hydrogen content of intermediate large polycyclic aromatic hydrocarbons (PAH), which is correlated with their molecular structure, plays an important role in t

The effect of chlorinated hydrocarbons on the formation of positively charged polycyclic aromatic hydrocarbons and fullerenes with masses up to 1300 U in benzene and butane flames

Autor: A.B. Fialkov, J. Dennebaum, K.-H. Homann

Publikováno v: Proceedings of the Combustion Institute. 28:2635-2641

The influence of chlorine-containing hydrocarbons on the formation of large polycyclic aromatic hydrocarbons (PAHs) in low-pressure flat flames of benzene and butane premixed with oxygen was studied. Because of the close relation between neutral and

Large molecules, radicals, ions, and small soot particles in fuel-rich hydrocarbon flames

Autor: A. Keller, K.-H. Homann, P. Weilmünster

Publikováno v: Combustion and Flame. 116:62-83

Large positive ions with masses up to 104 u have been studied in low-pressure, fuel-rich, premixed, flat acetylene/oxygen flames using molecular beam sampling with a reflectron time-of-flight mass spectrometer. The ions detected were those of polyyne

Large molecules, radicals, ions, and small soot particles in fuel-rich hydrocarbon flames: Part III: REMPI mass spectrometry of large flame PAHs and fullerenes and their quantitative calibration through sublimation

Autor: R. Kovacs, A. Keller, J. Ahrens, K.-H. Homann

Publikováno v: Berichte der Bunsengesellschaft für physikalische Chemie. 102:1823-1839

Large polycyclic aromatic hydrocarbons (PAHs) and fullerenes have been studied using nozzle/molecular beam sampling from flames and from a sublimator with subsequent resonance enhanced multi-photon ionization (REMPI) mass spectrometry. The mass spect

Large molecules, radicals ions, and small soot particles in fuel-rich hydrocarbon flames

Autor: K.-H. Homann, J. Griesheimer

Publikováno v: Symposium (International) on Combustion. 27:1753-1759

A fuel-rich, near-sooting, low-pressure, premixed haphthalene/oxygen/argon flame has been analyzed for condensible raction intermediates, mainly mono- and polycyclic aromatic hydrocarbons (PAHs), and for free radicals. Samples were taken through a no

Scavenging of hydrocarbon radicals from flames with dimethyl-disulfide II. Hydrocarbon radicals in fuel-rich low-pressure flames of acetylene, ethylene, 1,3-butadiene and methane with oxygen

Autor: K.-H. Homann, M. Hausmann

Publikováno v: Berichte der Bunsengesellschaft für physikalische Chemie. 101:651-667

The new technique of free-jet condensation/scavenging with dimethyl-disulfide has been applied for the quantitative analysis of hydrocarbon radicals and carbenes in flat premixed hydrocarbon/oxygen flames burning with fuel-rich mixtures at 27 mbar. T

PAH and aromers: Precursors of fullerenes and soot

Autor: M. Bachmann, W. Wiese, K.-H. Homann

Publikováno v: Symposium (International) on Combustion. 26:2259-2267

Positively and negatively charged flame ions in flat laminar low-pressure benzene/oxygen flames were analyzed by means of mass spectrometry. A rectangular burner consisting of two neighboring sintered plates was used to analyze concentration profiles
