Fig. 2

Methane oxidation rates as functions of a O2 pressure and b CH4 pressure were measured on 20 wt% B2O3/Al2O3. Reaction condition: 550 °C, 4–30 kPa PCH4, 0–80 kPa PO2 for a and 4–30 kPa PO2, 0–90 kPa PCH4 for b, balanced by N2, space velocity at 4920 mL gcat.−1 h−1. In a, the rate data measured at CH4 partial pressures of 4, 20, and 30 kPa are shown as black square, red cycle, and blue triangle, respectively. In b, the rates measured at O2 partial pressures of 4, 10, and 30 kPa were shown in black square, red cycle, and blue triangle, respectively. The curves in a and lines in b represent trends.
