Abstract

Based on thermodynamic calculations a discussion was given on the need for operation of the water-gas shift (WGS) reaction with a low H₂O/CO ratio when a H₂-separation membrane is combined with the reaction and on the degree of possible formation of C and CH₄ as the result of side reactions occurring in the mixture of CO, H₂O, CO₂ and H₂ under WGS conditions. The behaviour of a number of materials including Fe-Cr, Cu-Zn, Co-Cr and Pt/ZrO₂ were examined under the conditions where the ratio of H₂O to CO in the feed was low, with and without the presence of H₂S in the feed. The experimental results suggested that Pt/ZrO₂ has potential for use in these conditions.
