AbstractIn the current work, the high temperature water gas shift reaction assessment for hydrogen generation and its purification was carried out in reactors integrating hydrogen or carbon dioxide perm-selective membranes. Indeed, the performance of the high temperature water gas shift reaction was analyzed under adiabatic conditions through a mathematical model developed for this purpose. The main results indicate that both membrane reactors provide under some conditions a complete carbon monoxide conversion. As a result the dual phase membrane presents a great separation capacity of carbon dioxide. This gives us the opportunity to obtain a high purity of hydrogen. Thus, it can be concluded that the concept of the membrane reactor that used for carbon dioxide separation could be a veritable competitor and a great promise candidate for replacing the Pd based membrane reactors which is used for hydrogen separation.
