ABSTRACT

Using laser light extinction and emission of intermediate radicals C2 and CH, the pyrolysis of propane and methane was investigated by a shock tube technique. The experiments were carried out with the initial mixtures of 4% C3H8 + 96% Ar and 4% CH4 + 96% Ar in the temperature ranges 2100-3400 K and 2600-3700 K behind the reflected shock wave, respectively. The kinetic characteristics of the pyrolysis process − temperature profiles of the soot particle yield and the induction time of soot inception were determined. It is shown that the maximum yield in propane is observed in the interval of 2500-2600 K. The increase in the soot yield with temperature is typical of methane throughout the entire range investigated. As follows from the experimental data obtained, the temperature dependence of the induction time corresponds to the Arrhenius-like law.
Samples of the materials deposited on high-temperature decomposition were analyzed by the electron diffraction method, as well as using a transmission electron microscope. It is shown that the finely dispersed carbon particles formed in the pyrolysis of the propane-argon mixture have a predominantly amorphous structure, whereas in the case of the methane-argon mixture the presence of individual crystalline inclusions is noted.
