Abstract

Abstract: A Pt/Al2O3 metallic honeycomb catalyst was prepared and studied in the CO preferential oxidation. The surface of the Fe-20Cr-5Al metallic substrate (400 cells/in2) appeared needle shape structure when it was oxided at 900 ℃ for 10 h. The optimal Al2O3 coating procedure was slurry-sol-slurry. The metallic honeycomb catalyst showed CO conversion of 54.0% and CO selectivity of 42.5% in CO preferential oxidation at 120 ℃, which were 1.7 and 1.4 times that of the ceramic honeycomb catalyst, respectively.

Key words: metallic honeycomb catalyst, high-temperature oxidation, carbon monoxide, preferential oxidation
