Examination of Mechanisms and Fuel-Molecular Effects on Soot Formation.
Abstract
A variety of hydrocarbons has been pyrolyzed in a single-purse shock tube over the temperature range of 1000 to 2400 K and for dwell times of 500 to 700 microseconds. Gas samples of reactant, intermediate, and final products were collected and analyzed using gas chromatography. Experimental data were used in conjunction with a computer model to develop (or confirm existing) detailed chemical kinetic models for several of the hydrocarbons that were pyrolyzed. Model results agreed well with experimental data not only for the decomposition of the parent compound and formation of low molecular weight products, but also for the formation of single-ring aromatic species. These latter processes are believed to lead to the formation of polycyclic aromatic hydrocarbons, soot precursors, and eventually soot. Specific mechanisms and rate coefficients for the formation of aromatic rings have been proposed. Keywords: Acetylene, Vinylacetylene, Ethene styrene, 1,3,5-hexatriene, Biacetyl.
