摘　　要：建立了高温轴径向变换炉一维拟均相数学模型,根据以天然气为原料的日产1500 t天然气合成氨厂高温变换炉进口条件,确定轴径向变换炉的催化剂用量及主要设计尺寸,考察了进口温度、汽气比以及运行负荷对反应器性能的影响,结果表明:在进口温度350~390℃、操作弹性60%~110%条件下反应器均可满足设计要求,可供同类变换炉设计、操作参考。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.
