Figure 1. OCM reaction performance of the SrSnO3 and Nd2Sn2O7 catalysts. (A) CH4 conversion; (B) O2 conversion; (C) C2 selectivity; and (D) C2 yield. (E) Long-term stability test of SrSnO3 catalyst at 800 °C for 100 h. Reaction conditions: CH4/O2/Ar = 4/1/5, WHSV = 18,000 mL·h-1·g-1. OCM: Oxidative coupling of methane; WHSV: weight hourly space velocity.
