Fig. 13. CO2 conversion (A, top left), H2/CO ratios (B, top right) and CH4 conversion (C, bottom left) in the tri-reforming reaction over 100 mg supported Ni catalysts
at 1 atm and feed composition of CH4: CO2: H2O: O2 = 1: 0.48: 0.54: 0.1 (CH4 flow rate = 25 ml/min). Time-on-stream profile (D, bottom right) for CO2 and CH4
conversions in the tri-reforming reaction over Ni-MgO-CeZrO catalyst at 850 8C under 1 atm with feed composition of CH4: CO2: H2O: O2 = 1: 0.475: 0.475: 0.1
(CH4 flow rate = 25 ml/min, in a stainless reactor).
