STEAM REFORMING NI-BASED CATALYST WITHOUT PRE-REDUCTION TREATMENT

摘要

The present invention relates to a steam hydrocarbon reforming nickel-based catalyst requiring no pre-reduction treatment for the activity thereof. More particularly, the present invention relates to a steam hydrocarbon reforming nickel-based catalyst impregnated with Ru, Pt or a combination thereof in an amount of 0.001 wt% to 1.0 wt%, which can catalyze the reforming reaction even at 380 to 400 °C without being reduced with hydrogen in advance. According to the present invention, if it is impregnated with a small amount of ruthenium, platinum or a combination thereof, a nickel-based catalyst for use in small-sized fuel cells or in hydrogen stations can show steam reforming activity at low temperatures even without being reduced in advance. Thus, the catalyst requires neither apparatus nor complicated processes relevant to pre-reduction treatment, such as those for controlling reduction temperatures and flow rates, thereby being economically advantageous.
