%X In order to find the temperature range and initial reactant ratio for the maximum yield of acetylene, chemical thermodynamic equilibrium of heterogeneous multi-component C-H system was studied. All the thermodynamic equilibrium calculations are based on minimization of Gibbs free energy in the temperatures range from 500 K to 5000 K at intervals of 100 K. All species for which data are available in the JANAF Thermodynamic Tables are included in the C-H system. The Gibbs free energy minimization is expressed as a nonlinear optimization problem including equation and inequality constraints. The results show that it is irrational to consider the C-H system as homogeneous. Only the results from a heterogeneous system is realistic and reasonable and the best temperature range for acetylene formation is 3400~3800 K.
