| 초록 |
The complete oxidation of methane under realistic feed conditions containing water vapor normally requires high reaction temperatures above 500 °C over the typical platinum group metal(PGM)-based catalysts. A Pt-Pd bimetallic catalyst was developed to improve the low-temperature oxidation performance of methane under various oxygen concentration levels in the feed. The PGMs supported by alumina catalysts were prepared as a function of Pt:Pd ratio(1:0, 1:1, and 0:1) through the wet-impregnation method. The Pt:Pd-1:1 catalyst showed better oxidation activity than the Pd-only and Pt-only catalysts, where the better performance of the Pt:Pd-1:1 bimetallic catalyst appears to be on account of the superior steam reforming activity by Pt and the intrinsic oxidation activity by Pd. |
