Today, due to limited fossil fuel reserves as well as political, economic, and environmental constraints, the hydrogen energy source can be a long-term solution to the energy crisis. In this regard, in the present study, our main goal is to produce hydrogen during the ammonia decomposition process by the palladium membrane reactor system. Therefore, a study in the laboratory phase can be more expensive than simulation work. Therefore, in order to reduce laboratory costs in this project, for the first time, modeling and simulation of the performance of palladium membrane reactor system for hydrogen production during the process of ammonia decomposition by the dynamic fluid computational method in two-dimensional mode has been done. Therefore, due to this valuable modeling method, after comparing the model results with laboratory data to eva‎luate the validation of the model, eva‎luating the effect of various operating parameters such as pressure gradient, reaction temperature, feed flow on the performance of palladium membrane reactor has been done. From the results of computational fluid dynamics modeling, the good performance of the palladium membrane reactor for hydrogen production during the ammonia decomposition process is confirmed. In fact, the results of the eva‎luation of the palladium membrane reactor theory in some operating conditions show a better performance of 15% ammonia conversion and 60% hydrogen recovery at 723 K. This type of reactor with inhomogeneous flow is compared to a conventional reactor bedded during the ammonia decomposition process, which can be very promising in increasing the performance of chemical reactors.
