ABSTRACT:
A support for a fuel reforming catalyst includes aluminum (Al); and aluminum oxide (Al2O3) encapsulating the aluminum, wherein a total volume of micropores and mesopores is in the range of 0.1 to 1.0 ml/g per unit mass, and a volume of macropores is in the range of 0.4 to 1.2 ml/g per unit mass, and a method of preparing the same. The support has excellent heat transfer characteristics due to its high thermal conductivity and excellent mass transfer characteristics because the micropores, mesopores, and macropores exist in a proper ratio. Accordingly, if the support is used for a supported catalyst that is used in a reaction, in which the reaction rate is controlled by heat transfer and mass transfer, such as a fuel reforming reaction, the activity of the catalyst is enhanced. In addition, the support can be easily formed as desired due to its high mechanical strength.
