A simulation study of a membrane reactor for the water-gas shift reaction is presented. A pseudohomogenous1D mathematical model is considered to describe the performance of the membrane reactorunder steady-state operation. The membrane consists on a dense Pd layer (selective to H2) depositedon a porous ceramic support. The influence of operating pressure and thermal effects on the membranereactor performance is analyzed and the results are compared with those corresponding to a reactor withno hydrogen permeation.
