摘要：

Steam reforming of methanol (CH(3)OH4H(2)O-->3H(2)+CO2) has been performed on a stable AlCuFe quasicrystal. The AlCuFe quasicrystal reveals excellent activity after leaching treatment. The production rate of H-2 reaches 235 1/kg.min at 553 K. The quasicrystals have two advantages: one is their brittle nature, which allows them to be crushed efficiently; the other is thermal stability as a catalyst support, which make their high temperature application possible. Catalysts prepared from Al-Cu-Fe alloys with various compositions were also evaluated. Al63Cu25Fe12 was shown to have the highest activity per unit area among Al-Cu-Fe alloys.
