Abstract : A computer model was developed to relate pyrolysis and soot formation to fuel properties. A Fourier Transform-Infrared Spectrometer (FT-IR) was used to characterize the effect of temperature, pressure, reaction time, and hydrogen and oxygen concentration of fuels undergoing pyrolysis. The problem of how to identify and measure the hydrogen available for release during pyrolysis was investigated. A detailed data base of a variety of fuels undergoing pyrolysis was developed. The data base conditions included: temperature 800-1500 C; pressure 1-15 atm; and reaction time 100ms-1 sec. Experimental data results show that fuels decompose to form small hydrocarbon species prior to the onset of soot formation. A hydrocarbon model was extended to include Rice-Kossiakoff-Herzfeld mechanism to predict the decomposition of long chain aliphatics to small molecules. A free radical soot model was developed to predict the growth of soot precursors from the small molecules. Keywords: Combustion pyrolysis model; Soot formation; Fourier transform-infrared spectroscopy; Rice-Kossiakoff-Herzfeld mechanism; Free radical.
