摘要

考察了SnO2/MgO催化剂和添加助剂V、Mn对二甲醚（DME）催化氧化制取乙二醇二甲醚（DMET）和其他碳氢化合物的催化性能。结果表明，锡镁催化剂对DME在275～325 ℃有良好的催化活性；添加VOx能较大提高DME转化率和产物DMET的选择性，DME转化率可达23％，DMET选择性可达44％，在300℃收率达9％以上。

Abstract

Selective oxidation of dimethyl ether（DME）to dimethoxyethane（DMET）and other hydrocarbons over SnO2/MgO and V or Mn modified catalysts was investigated. It was found that all the catalysts were active for the reaction in the temperature range of 275—325℃. DME conversion and the selectivity of DMET increased when adding V or Mn to the SnO2/MgO catalyst. The selectivity of DMET reached 44% at a DME conversion of 23% on VOx/SnO2/MgO catalyst，which is higher than those of SnO2/MgO or Mn modified SnO2/MgO catalysts.
