中文摘要：

甲醇是重要的基础化工原料,随着全球甲醇产能过剩,将甲醇催化转化为高附加值的甲醇下游化学品具有重要意义,其中甲醇一步催化转化为甲缩醛（DMM）和甲酸甲酯（MF）等高附加值甲醇下游化学品备受人们的关注,而这一过程中的双功能催化剂是关键。本文对近几年来甲醇催化转化一步合成甲缩醛和甲酸甲酯的双功能催化剂体系进行了总结和评述,特别是对贵金属催化体系、金属氧化物催化体系、杂多酸催化体系等双功能催化剂的催化作用和产物分布特点进行了仔细分析,以期对甲醇催化转化一步合成甲缩醛和甲酸甲酯的工艺放大提供一些参考。

英文摘要：

Methanol is a kind of important basic chemical raw material. With the increase of global methanol production capacity,the catalytic conversion of methanol to methanol dow nstream high value-added dow nstream products is very important. The bifunctional catalysts for one-step oxidation of methanol to dimethoxymethane（ DMM） and methyl formate（ MF） with high value-added are very useful and have received considerable attention. In this paper,the recent applications of bifunctional catalysts for one-step oxidation of methanol to DMM and MF in recent are reviewed and summarized. The catalysis of bifunctional catalysts and the distribution of the products,especially the precious metal catalysts,metal oxide catalysts and heteropolyacid catalysts are carefully analyzed in order to provide a wide range of references for the catalytic conversion of methanol through synthesis step process of DMM and MF.
