... using various reducible metal oxides as oxygen carriers as well as catalysts. A typical reaction can be represented by 2 CH4 + MOx + 2 = C2H4 + 2 HALO + MOx, where MOx + 2 and MOx represent the metal oxide and reduced metal oxide, respectively.

From page 199...
... CATALYTIC PYROLYSIS Direct methane conversion through catalytic pyrolysis involves contact of methane with a catalyst at a relatively high temperature (1100° to 1200°C) , pressures near about 1 atm, and at a short contact time.
