Abstract： In order to rationally optimize the residence time of propane pyrolysis process in a thermal plasma reactor, the rotating arc plasma reactor was regarded as one-dimensional plug flow reactor network model to analyze the concentration and temperature distributions of the propane pyrolysis in the thermal plasma reactor using the pyrolysis reaction kinetic model and the flow model of the reactor to mathematically simulate the pyrolysis process of propane by CHEMKIN-PRO software. The plasma pyrolysis process of propane was investigated from homogeneous and heterogeneous reaction models, respectively. The simulation results indicated that the heterogeneous reaction kinetic model with the soot formation model was in agreement with the experimental results. With the increase of the reactor length, there was an optimum concentration point of acetylene and the yield of acetylene could be efficiently improved by reducing the residence time of plasma reactor to 1.0 ms.
