영문 초록

This study was coducted to find a catalyst system which has high conversion and selectivity for the oxidative coupling of methane to produce ethane and ethylene. Various catalysts were tested in a fixed bed reactor ar 750℃, 1 atm, and the feed rat1o(CH₄/O₂) of 2/1. Under the reaction condition, 10wt% PbSO₄/MgO catalyst showed the highest catalytic activity : methane conversion, C₂ selectivity and yield were 50, 40 and 20%, respectively. Catalysts contaning sulfate compounds, 1Owt% PbSO₄/MgO, l0wt%MgSO₄/MgO and Na₂SO₄/MgO revealed a moderate methane conversions such as 38, 50 and 50%, respectively and low C₂selectivities such as 18, 5 and 9%, respectively. Catalysts contaning carbonate compounds, 10wt%PbCO₃/MgO, 10wt%Li₂CO₃/MgO and NaCO₃/MgO, also showed a moderate methane conversions such as 64, 44 and 51 %, respectively and low C₂ selectivities such as 5, 6 and 2%, respectively. With the existence of chlorine and mercury, C₂selectivity was decreased.
