Abstract : The CO2 -CH4 autothermal reforming process is calculated and analyzed by the Gibbs free energy minimization method and Computational Fluid Dynamics (CFD) coupled with detailed reaction kinetics . Combining with independent research and development reactors and catalysts , the pilot test conditions were the raw material gas treatment capacity of 10 o00m/h,operating pressure of 2MPa, nickel based catalyst loading of about 5 tons, and the syngas was CH4 /syngas ratios less than 1% , n(H2 )/n(CO)=1.l and effective gas content of 60.7% on the Low Carbon Circular Economy Park , Shanxi Lu'an Coal-to-Gasoline Co., Ltd. The main design dimensions of CO:-CH+ autothermal reforming reactor were the inner diameter of l.6 m, the combustion height of 3.0 m, the catalyst loading height of 2.8 m and the reactor overall height of about 13 .8 m
