摘要

考察了4种分子筛HZSM-5、Hβ、HY、Al-MCM-41及Mn、Mo、Co、Cu改性的HZSM-5型分子筛催化剂对二甲醚（DME）催化氧化制碳氢化合物的反应性能。结果表明，HZSM-5分子筛在275～325 ℃具有较高活性；二甲醚的转化率在Mn改性的HZSM-5分子筛催化剂上有较大提高，275 ℃时达到27. 8 %，甲酸甲脂（MF）的收率可达6. 9 ％。并在生成产物的基础上推测了二甲醚催化氧化的反应机理。

Abstract

The selective oxidation of dimethyl ether（DME）to methyl formate and other hydrocarbons over four zeolites，namely HZSM-5，Hβ，HY and Al-MCM-41，and metal（Mn，Mo，Co，Cu）modified HZSM-5 catalysts were investigated by using DME and O2 as reactant gases and helium as diluent with a mole ratio of 5∶1∶6 under a pressure of 0. 1 MPa. It was found that the modified HZSM-5 zeolite catalysts were active for the reaction in the temperature range of 275—325℃. The conversion of DME was increased to 27. 8 % at 275℃ with a methyl formate（MF）yield of 6. 9% over the Mn modified HZSM-5 zeolite. Possible reaction mechanism was discussed as well.
