| Abstract: | 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. |
