Carbonylation of dimethyl ether to form methyl acetate has attracted much attentions, as an important step of an indirect synthetic route of ethanol. Cu dopant zeolites are intensively investigated, due to their good activity, excellent selectivity, low price and easy preparation. In this work, we focus on understanding the influence of Cu species on catalytic properties and deactivation in carbonylation of DME. The synergistic effect between cooper species and Brønsted acid sites in catalysis are demonstrated. The effect of Cu loading and preparation methods are discussed detailedly. In addition, TPD-MS, TG, IR, UV-vis and NMR are introduced to explain the different deactivation phenomenon over H-MOR and Cu/H-MOR, based on the analysis of coke formation.
