 A highly stable, active, non-methane and carbon forming catalyst is required for use in a membrane reactor to produce high purity H2 through the WGSR. In such a process, the catalyst should operate at ca. 673 K as a compromise between the  impairing effect of CO upon the H2 permeability and the thermal deterioration of the membrane. In a previous work, a Rh/La2O3.SiO2 catalyst was characterized and used in the WGSR. However, this catalyst promotes methanation under membrane reactor conditions. In this work, a stable, active and well-characterized Pt catalyst is presented,  which minimizes the formation of methane. Its performance in the membrane reactor is reported.
