Hydrogen is attracting much attention as a clean and efficient energy source. In Ni-Al system there are four stable intermetallic compounds, NiAl3, Ni2Al3, NiAl, and Ni3Al. Among them a mixture of NiAl3 and Ni2Al3 (Ni-50 wt% Al) is used as a precursor alloy for Raney nickel catalysts: the Raney nickel catalysts are produced from the precursor alloy by leaching aluminum in a concentrated NaOH solution. For NiAl and Ni3Al, very limited studies have been carried out on the catalytic properties. The catalytic activity and stability of single-phase Ni3Al (Ni-24 atom % Al) powder for hydrogen production from methanol at 513-633 K was studied. The alkali-leached Ni3Al powders showed a high catalytic activity and stability for the methanol decomposition. The rate of hydrogen production increased rapidly with increasing reaction temperature. The Ni3Al catalysts suppressed the formation of methane and waster gas shift reaction, i.e., they showed higher selectivity for methanol decomposition than nickel catalysts. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
