“…The selectivity can be improved in composite membranes that consist of a thin membrane layer deposited into a porous support via electrodes plating or sputtering: the permeability and selectivity depend on the coverage of the support pores by the membrane layer [25,26,27]. In this membranes, higher hydrogen permeability, increased mechanical resistance, lower cost respect to unsupported membranes are achieved as described by Anzelmo et al [28], describing also the effect of different parameters as reactor pressure and permeate sweep gas rate on methane conversion, hydrogen recovery and hydrogen permeate purity.…”

Natural gas steam reforming due to the abundant availability of natural gas is the principal way to produce hydrogen. Higher purity of hydrogen can be obtained with membrane reactor. An integrated membrane reactor that useNi(10)/CeLaZr catalyst supported on SSiC ceramic foam is analyzed in this research. Respect to other literature works, foam catalyst is used in place of common pellet catalyst to have better performance of the process with higher distribution of temperature. A rating mode is carried out founding the correct heat transfer coefficient of the reactor. A modeling of the reactor is carried out in Aspen Plus using the correlation presented in literature for the catalyst foam, Sieverts' law and Numaguchi kinetic. The commonly used Xu and Froment kinetic is replaced by Numaguchi kinetic. Results on reactor performance show satisfactory agreement with experimental data. A study of methane conversion, hydrogen recovery, temperature of reactor, hydrogen partial pressure versus reactor length and membrane permeability is performed. The membrane permeability has positive effect on methane conversion and hydrogen recovery. For the other parameters the effect is negative. Future works should optimize the operation of the integrated membrane reactor to have the higher hydrogen production and methane conversion.

The most widely used process for hydrogen production is steam methane reforming. It can be carried out using a membrane reactor in which simultaneous hydrogen production and purification occur. Mathematical modeling of these reactors plays a key role in the selection of the design and operating parameters that yield high performance for the reactor. This review study discusses, synthesizes, and compares different mathematical modeling studies on the packed bed membrane reactors for hydrogen production from methane found in the literature. Different approaches used in these modeling studies for the hydrogen permeation steps, reaction kinetic expressions, phases involved (pseudo-homogeneous and heterogeneous), and spatial dimensions (one, two, and three dimensional) are given.
