Abstract—A simulation study of a double tubular catalytic membrane reactor for the water–gas shift (WGS) reaction under steady-state operation is presented. The membrane consists of dense Pd layer deposited on a porous glass cylinder support. The WGS model was carried out with and without the membrane at a temperature of 673 K, pressure of 2atm, argon flow rate of 400 cm
3.min
−1, and steam-to-carbon (S/C) ratio of 1. The membrane reactor could achieve a Carbon Monoxide (CO) conversion efficiency of up to 93.7%, whereas a maximum value of only 77.5% was attained without using a membrane. In order to find the optimum operating conditions, the response surface method was used. It was found that a nearly complete CO conversion could be achieved at S/C ratio = 4, total retentate pressure =12 atm, and membrane thickness =5 μm. There is a good agreement between the model results and the reported experimental results.
