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.
