LFG (Land-Fill Gas) includes components of CH₄, CO₂, O₂, N2, and water. The preparation of synthesis gas from LFG as a DME (Dimethyl Ether) feedstock was studied by methane reforming of CO₂, O₂ and steam over NiO-MgO-CeO₂/Al₂O₃ catalyst. Our experiments were performed to investigate the effects of methane conversion and syngas ratio on the amount of LFG components over NiO-MgO-CeO₂/Al₂O₃ catalyst. Results were obtained through the activity reaction experiments at the temperature of 900°C and GHSV of 4,000. The results were as following; it has generally shown that methane conversion rate increased with the increase of oxygen and carbon dioxide amounts. Highly methane conversion of 92~93% and syngas ratio of approximately 1.0 were obtained in the feed of gas composition flow-rate of 243ml/min of CH₄, 241ml/min of CO₂, 195ml/min of O₂, 48ml/min of N2, and 360ml/min of water, respectively, under reactor pressure of 15 bar for 50 hrs of reaction time. Also, it was shown that catalyst deactivation by coke formation was reduced by excessively adding oxygen and steam as an oxidizer of the methane reforming.
