Abstract Syngas production from coke oven gas(COG) with non-catalytic partial oxidation(NCPO) was simulated with Curran detailed reaction mechanism using Chemkin software. Concentration of the main species evolved with time and the effects of operation parameters, such as reaction temperature, reaction pressure and molar ratio of O2 to COG, on the dynamic time, syngas mole fraction and molar ratio of H2 to CO, were investigated. The simulation results showed that under the industrial relevant operating conditions, the simulated syngas(H2+CO) mole fraction and molar ratio of H2 to CO were in agreement with the industrial data, the scale of COG with NCPO dynamic time was ms. The higher the reaction temperature, the shorter dynamic time. At the temperature above 1 373 K, dynamic time did not reduced obviously. The bigger the reaction pressure, the shorter the dynamic time. After the pressure increase to 3.0 MPa, dynamic time reduced slightly. The higher the molar ratio of O2 to COG, the shorter the dynamic time, but the lower the syngas mole fraction and the molar ratio of H2 to CO. As the molar ratio of O2 to COG was more than 0.262, molar ratio of H2 to CO did not descend evidently, keep in the range of 2.0-2.5.
