Reactor of ammonia synthesis is one of key equipments for ammonia manufacture. MATLAB is adopted to simulate the axial and/or radial flow ammonia synthesis reactor, which is described as one dimension homogeneous model. In this program, graphics user interface （GUI） is developed for the reactor simulation by using GUIDE of MATLAB. MAPLE functions and application programming interface （API） for excel, offered by MATLAB, were applied to improve GUI and design file I/O. It realized the transform between character string and numerical value by MAPLE, which makes the input of the different kinetics equation of ammonia synthesis conveniently. By applying this program, axial bed, radial bed, and their combination can be easily computed. The simulating results show that the data calculated by this program is reliable. It is demonstrated GUIDE of MATLAB language is a good helper of developing simulation program of ammonia synthesis reactors, which can reduce the heavy task of programming, give useful graphics user interface, and improve the efficiency of designing ammonia synthesis reactor.
