摘要：在柱坐标系中建立了描述三套管氨合成塔催化床径向浓度和温度分布的数学模型.采用网格法计算了管间催化床不规则截面的浓度分布和温度分布.计算方法快速、有效.
In this paper, a two-dimensional mathematical model discribing the radial concentrations and temperature profiles in the catalytic bed of triple tube type ammonia synthesis reactor was established in the cylindrical coordinate system. The concentrations and temperature profiles in an irregular cross section of catalyst bed between cold tubes were calculated by the mesh -point method. The calculation is not time-consuming,so that the method is an effective one.
