Non catalytic partial oxidation of coke oven gas (COG) was numerically simulated with a detailed chemical kinetic model that consists of more than 200 chemical species and more than 2000 elementary step like reactions. COG was model as a mixture of H_2, CO, CO_2, CH_4, C_2H_6, C_2H4_, benzene, toluene, xylene, and tar which was lumped into 6 kinds of polycyclic aromatic hydrocarbons. The simulation suggests that oxygen is consumed almost completely for the combustion of reactive light gases such as hydrogen, CO, CH_4, and C_2 hydrocarbons within a reaction time of 0.02 seconds. Oxygen doesn't contribute directly to the tar reforming but it induces temperature increases of the reacting gas by the combustion and accelerates reforming of the tar by steam.
