Abstract: One-dimensional pseudo-homogeneous model of an axial flow converter and one-dimensional
heteroge-neous model of a horizontal converter have been presented, which describe the
distribution of gaseous composition,temperature and pressure along the height in the two
converters, respectively. Design optimization methods of the two converters have been
proposed, by which the minimum catalyst volume can be obtained to satisfy the productive
capacity of 1000 tons per day, when the operating pressure is 15.0, 10.0 and 7.5 MPa,
respectively.

Key words: ammonia synthesis, axial flow converter, horizontal converter, mathematical model, design optimization
