| 中文摘要 | The SnO2-doped 5% Na2WO4-2% Mn2O3/SiO2 catalyst for oxidative conversion of methane to high hydrocarbons has been studied in a micro-stainless-steel reactor at elevated pressure. At 1053 K, 1.0 × 105 h−1 GHSV and 0.6MPa, a CH4 conversion of 33.0% with C2+ selectivities of 73.1% is obtained; here the C2, C3 and C4 hydrocarbons selectivities of 36.8, 14.2 and 22.1% are observed. On addition of SnO2, conversion of methane and selectivities of C3–C4 hydrocarbons increase obviously. The observed results showthe storage-oxygen capability in Na-W-Mn/SiO2 catalyst is enhanced with adding SnO2, for Mn and Na2WO4 migrate to near-surface to result in a marked shift to higher molecular weight products. The distribution of products at the operating conditions and content of SnO2 loading has been described. |
