Figure 3

Thermal pretreatments and onset of steady state CH4 oxidation over Cu-Na-ZSM-5 (Cu/Al = 0.37). (A) Thermal pretreatments, reaction conditions for all pretreatments, and catalytic CH3OH production rates. The symbol ± denotes 95% confidence interval. (B) Evolution of catalytic CH3OH production for each pretreatment outlined in (A); t = 0 denotes when the CH4/H2O/O2 gas flow was started. Reaction conditions: T = 483 K, WHSV = 2400 mL h–1 gcat–1, PCH4 = 98.1 kPa, PH2O = 3.2 kPa, PO2 = 0.0025 kPa.
