Modern Ni and Pd-Ni Catalysts Supported on Sn-Al Binary Oxide for Oxy-Steam Reforming of Methanol

摘要

Monometallic Ni and bimetallic Pd-Ni catalysts supported on mono-SnO2 and SnO2-Al2O3 binary oxide are prepared using a wet impregnation and subsequent impregnation method. The catalysts are tested in oxy-steam reforming of methanol (OSRM) and characterized. The activity measurements show that palladium-promoted nickel catalysts supported on SnO2-Al2O3 exhibit high activity, selectivity towards hydrogen formation, and stability. The effect of Pd on reducibility, surface acidity, and morphology of the Ni supported catalyst, as well as its catalytic properties in OSRM, are discussed in detail.
