Abstract: A heterogeneous one-dimensional model was developed to simulate the axial-radial high-temperature adiabatic shift converter. According to the conditions of feed gas to the high-temperature shift converter in a 1500 t/a ammonia plant, the catalyst loading and dimensions of the axial-radial shift converter were determined. The effects of some operational parameters such as inlet temperature, steam gas ratio and operating load on the behavior of the shift converter were investigated. The simulation results show that when the inlet temperature ranges from 350℃ to 390℃ and the capacity ranges from 60% to 110%, the high-temperature shift converter can meet the process requirements.
