Dynamic simulation of industrial steam reforming reactor has been considered in the presence of catalyst deactivation. The performance of the reactor was investigated using a heterogeneous model. For process simulation, the differential equations are solved using 4th order Runge-Kutta method .The models were validated against measured process data of a steam reforming plant. The results of simulation in terms of components yields and temperature of the outlet are in good agreement with empirical data. The simple model displays a useful tool for dynamic simulation, optimization and control of steam reforming
