We have employed 800 nm 150 fs laser pulses to carry out photoionization (PI) time-of-flight mass spectrometric detection of intermediates following corona discharges on aromatic molecules (alkylbenzenes and pyridine) in He, stabilized by subsequent supersonic gas expansions. Observed product peaks appear to be at least roughly in proportion to actual number densities; PI induced fragmentation of parent ions appears not to be excessive. Consequently, 800 nm fs PI should be useful for general product analysis applications in plasma chemistry. For most alkylbenzenes subjected to corona discharges in rare gas, the overall trends in product chemistry are similar in many respects to observed flame and pyrolysis chemistry in rare gases for the same species. Following discharge, as in those other cases, H deficient carbon radical fragments initially produced react in turn to form larger aromatic species. However, compared with flame/pyrolysis, discharge produced a larger number of fragment species, which can lead to a wider and somewhat different range of higher mass aromatic products. Co-addition of even a small component of O 2 to the discharge mixes has a potent effect in inhibiting formation of higher mass aromatic products in alkylbenzenes.

“…Whereas experimental investigations of such benzene flames have been carried out by a few groups [4][5][6][7][8], they only concern rich benzene flames with equivalence ratios of 1.8 and 2. The pioneering works of Bittner and Howard [4] have been used for the development of many detailed kinetic mechanisms [9][10][11][12][13][14][15][16].…”

One-dimensional laminar premixed benzene-oxygen-argon flames with equivalence ratios of 2, 1, and 0.7, stabilized at low pressure (45 mbar) on a flat flame burner are studied. Gas sampling is performed by a conical quartz nozzle, at different positions in the flames. Identification and monitoring of chemical species is performed by gas chromatography. These measurements should complete experimental data on rich and sooting benzene flames available in the literature and will be of particular help for further improvements of benzene oxidation mechanisms. A comparison of experimental results with data simulated with the use of two recent kinetic models highlights their inability to predict stoichiometric and lean benzene combustion.

“…It is important on a numerical simulation of a coal flame because the ignition of coal volatile is one of the major issues to evaluate the characteristics of the coal type. Figure 6 shows the comparison of mole fractions between the experimental data and the computations, (a) fuel rich ethylene-oxygen-argon flame with C/O = 0.76, 20 torr, 50 % argon and cold gas velocity = 62.5 cm s -1 by Bhargava and Westmoreland (1998) and (b) benzene-oxygen-argon flame with C/O=0.71, 30 torr, 50 % argon and cold flow rate = 32.7 cm s -1 by Yang et al (2007). The profile predicted by DAP is also displayed to compare in each figure.…”

Reaction kinetics of coal volatile were numerically investigated based on analyses during reaction mechanism reduction procedure in detail in this paper. Computation on a closed homogeneous reactor model was performed to clarify important chemical species and their reaction pathways with evaluating the capability of prediction of ignition delay time and chemical species concentration under a wide range of equivalence ratios and temperatures. The kinetics of large hydrocarbons such as polycyclic aromatic hydrocarbons (PAH) that comprise a large portion of combustion features for complex hydrocarbon materials was focused on in a coal flame. The data computed here was analyzed through the combined process of the directed relation graph with error propagation and sensitivity analysis (DRGEPSA) and the computational singular perturbation (CSP) that can evaluate the roles of each species and reaction pathway respectively in the chemical system. Results show that hydrocarbons such as aromatics, methyl and ethyl groups play important role in the ignition and flame propagation processes. Finally, the skeletal mechanism including 64 species and 150 reactions was derived from the detailed mechanism that consists of 257 species and 1107 reactions within 30% error in the prediction of the ignition delay time and the mole fractions of major species in the propagating flame.
