In this work, a simulation of a fixed bed reactor for water gas shift reaction, which forms part of a hydrogen production, was carried out. A commercial CuO/ZnO/Al2O3 catalyst was employed and a one-dimensional heterogeneous model was applied for the simulation. The kinetic information has been taken from literature for the above reaction. The distribution of concentration in fluid bulk as well as porous catalyst, rate of reaction, pressure profile and superficial velocity distribution were represented as results of study. gPROMS, a general purpose modeling package, was used for modeling and simulation of the water–gas shift reaction.
