Chemical overshoot during shock pyrolysis of organic molecules
Abstract
C2 Swan band emission measurements for methane and ethylene shock pyrolysis show similar features to those reported for acetone.1 Equilibrium emissivity measurements for all three molecules are in good agreement with computer calculations of C2 concentrations. For richer mixtures the endothermic fragmentation immediately behind the shock front is followed by exothermic recombination to achieve chemical equilibrium.
