Figure 5. Effect of reaction temperature on methane conversion and Ni-normalized carbon productivity over 050Ni-LCCM and 150Ni-LCCM catalysts. (A and B) Methane conversion as a function of time on stream over (A) 050Ni-LCCM and (B) 150Ni-LCCM at 700-850 °C; (C) Ni-normalized carbon productivity at different reaction temperatures. The experiments were conducted in a rotary reactor at 1 rpm for 8 h with a space velocity of 3 L·gcat.-1·h-1. Error bars represent the standard deviation of three independent tests performed at 750 °C. This temperature was selected as the representative reaction condition for reproducibility verification. LCCM: (La0.75Ca0.25)(Cr0.5Mn0.5)O3-δ.
