Development of Microstructured Catalytic Wall Reactors for Hydrogen Production by Methanol Steam Reforming over Novel Pt/in2o3/al2o3 Catalysts

Abstract

Methanol steam reforming was investigated over novel Pd/In2O3/Al2O3 and Pt/In2O3/Al2O3 catalysts coated into microchannels. The investigations revealed, that Pt is much more active at still moderate CO selectivity compared to Pd. An In2O3 content of 25 – 30 wt.% was required to minimize the CO selectivity of the Pt-containing samples. At a Pt/In ratio of 0.6, the catalyst with the highest Pt content of 15 wt.% showed also highest activity. Switching to conditions of oxidative steam reforming further increased the activity of the catalysts.
