This study focuses on the syngas production by partial oxidation of coke oven gas (COG). The reforming of COG, which is a multi-component mixture, in a turbulent flow includes various complex processes. Previous studies were limited to the results using simulated gas with a laboratory scale small reactor and a laminar flow. In this study, we developed a model which considers both chemical reactions and fluid dynamics for simulating the reforming characteristics of the actual COG in a bench scale relatively large reactor. The detailed chemical kinetic model which consists of more than 2000 elementary reactions and 257 species was reduced to 410 reactions and 47 sepcies for realizing coupling a finite rate reaction model with the turbulence model. Numerical simulations could fairly reproduce the reformed gas compositions and temperature profiles in a reformer.
