Modeling of Membrane Reactors for Hydrogen Production and Purification... 

The success of membrane reactors for hydrogen production is basically associated with (i) the advances in membrane production methods and (ii) the design of innovative reactor concepts, which allow the integration of separation and energy exchange, the reduction of mass and heat transfer resistances and simplification of the housing of the membranes. 

Different types of membrane reactors for hydrogen production have been proposed in the literature. Most of the previous work has been performed in packed bed membrane reactors (PBMRs) however, there is an increasing interest in novel configurations such as fluidized bed membrane reactors (FBMRs) and membrane micro-reactors (MMRs), especially because better heat management and decreased mass transfer limitations can be obtained in these novel reactor configurations. 

Modeling of Membrane Reactors for Hydrogen Production and Purification and the energy balance for the solid phase is ... 

The application of ID models is quite useful in describing the axial temperature and concentration profiles inside the reactor, while accounting for the effects of intra-particle mass transfer limitations, and membrane characteristics on the reactor performances and is useful for a first design of the membrane reactor. A big limitation of such a model is that radial profiles are ignored. If one considers that in packed bed membrane reactors for hydrogen production, the hydrogen should migrate from the catalytic bed (where it is produced) to the membrane surface (where it permeates), it is clear that radial profiles can be... 

In the following section a two-dimensional model will be described that is used for the computation of temperature and concentration profiles inside a packed bed membrane reactor for hydrogen production. For simplicity, only a pseudo-homogeneous model will be described. The extension of the heterogeneous model is analogous to the ID model. 

This model, applied to a packed bed membrane reactor for hydrogen production through methane reforming can give in particular indications on the extent of mass transfer limitations. 

A typical ID two-phase model for a membrane assisted fluidized bed reactor can be used for the simulation of the fluidized bed membrane reactor for hydrogen production via methane reforming. A schematic representation of the gas flows between the compartments of the bubble and emulsion phases is depicted in Figure 10.6. The model main assumptions are ...
