Mechanism of Momogeneous Thermal Oxidation of Ethane

抄録

Homogeneous thermal oxidation of ethane-oxygen mixtures, highly diluted with argon, was studied in shock waves by the following emission and absorption of various species in the course of their reaction. The equivalence ratio φ= 3.5 [C₂H₆]/[O₂] was varied from O.2 to 2.0. The total density extended from 10^-5 to 10^-4 mol/cm³, corresponding to 0.1 to 1.0 MPa (1 to 10 atm) at 1400 K. For highly diluted mixtures the experiments indicate an influence of argon density on the induction period. In order to obtain the mechanism of the oxidation of ethane-oxygen mixtures, molecule and fadical profiles were calculated by the numerical integration of 58 reactions and compared with the experimental results. The calculated results agreed well with those experimentally determined. From this comparison a reaction schema from ethane oxidation was proposed.
