ABSTRACT

A metal monolithic anodic alumina supported nickel catalyst with a trace amount of doped noble metal, were prepared to investigate its activity for the steam reforming of hydrocarbons. In comparison with commercial catalysts, the anodic alumina catalyst showed an excellent activity and durability, not only in steam reforming of methane but also kerosene and ethanol. When using town gas 13A as hydrogen source, no obvious deterioration was detected over the Pt-doped Ni catalyst in a stationary test of 3000 h and a DSS field test of 500 times. Besides its multi-purpose, the noble metal doped Ni catalyst was found to have some additional advantages, for example, self-activation, robustness against steam purge, and favorable performance in daily start-up and shut-down (DSS) operation. When innovatively using electrical heating pattern to heat up the catalyst, the Pt-doped Ni catalyst was observed to quickly initialize SRM reaction within 15 min, and no deactivation was observed during 20 h stationary test at 700°C.

Keywords: Steam reforming, Multipurpose catalyst, Anodic alumina catalyst, Methane, Kerosene.
