Examination of Mechanisms and Fuel-Molecular Effects on Soot Formation.

Abstract

Acetylene, vinlyacetylene, and benzene have been pyrolyzed in a single-pulse shock tube over the temperature range of 1000 to 2400K and for dwell times of approximately 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 and decomposition of single-ring aromatic species. The formation processes are believed to lead to the production of polycyclic aromatic hydrocarbons, soot precursors, and eventually soot.
