Abstract
A compact mechanism based on elementary radical reactions is proposed for the temperature conversion of methane-ethane mixtures. The kinetic model relying on this mechanism describes the literature data on the conversion of methane and ethane at millisecond time intervals in the temperature range 600-1400 °C. Within the kinetic model, the time dependences of the concentrations of hydrogen, ethylene, acetylene and benzene on the temperature and on the methane/ethane ratio in the initial mixture are determined in the isothermal approximation. Using the proposed mechanism for the calculations of axisymmetric gas dynamic flows of reagents mixture, the yields of hydrogen and valuable unsaturated hydrocarbons in a non-isothermal tubular reactor are determined.
