Numerical Modeling on Catalytic Tri-reforming Reaction of Methane for Syngas Production

摘要

In this study, a two-dimensional numerical model was built to study the tri-reforming of methane (TRM) in a tubular fixed-bed reactor under various operation pressures, inlet temperatures, and reactant compositions. It was found that TRM cannot be activated if the reactant inlet temperature were too low. With lower O2/CH4, higher H2O/CH4 and lower CO2/CH4 ratios in the reactant composition, higher H2/CO ratio can be obtained. It was also found that water-gas shift (WGS) reaction played an important role for controlling the resulted H2/CO ratio in syngas.
