Abstract

Catalytic oxidation of methanol was investigated using Pd, Pt and Ru-based catalysts. Experiment was conducted at reaction temperature of 100∼220 °C with methanol concentration of 3,000 ppm and gas hourly space velocity (GHSV) of 16,000 hr^-1. Catalysts were characterized by using Brunauer-Emmett-Teller (BET) method, X-ray diffraction (XRD), field transmission electron microscopy (FE-TEM) and temperature programmed reduction (TPR). Based on complete oxidation temperature of methanol, the activity order was: 0.16 wt% Pd /0.16 wt% Pt/0.16 wt% Ru/γ-Al₂O₃ > 0.5 wt% Pt/γ-Al₂O₃ > 0.5 wt% Ru/γ-Al₂O₃ > 0.5 wt% Pd/γ-Al₂O₃. Therefore, the activity of ternary metal-based catalyst was superior to single metal-based catalyst.
