英文摘要	By using zeolite-supported alkali methoxide liquid-film catalysts, such as KOCH3- PEG/NaZSM-5 (or NaY), the heterogeneous catalytic carbonylation of methanol to methyl formate was realized in a fixed-bed continuous flow reactor. Under the reaction conditions of 353 K, 1.0 MPa, feedgas composition of CO/CH3OH = 6.48 (molar ratio) and GHSV = 11 160 h(-1), the STY of MF reached up to 1 900 mg/(h.g cat.), with selectivity to MF at 100%. The experimental results indicated that methoxide anion CH3O- was crucial catalytically active species. The role of the additive polyethylene glycol(PEG) in generating a liquid film environment, in which the carbonylation reaction would take place, is important, especially in the case of supports with large pore-diameter as SiO2. However, in the case of some support materials with abundant micropore structure such as ZSM-5 or Y-type zeolite, it is probable to design and select appropriate reaction conditions(mainly, temperature and partial pressure of methanol in feedstream) to generate directly liquid-film of methanol by means of the ''capillary condensation effect'', as a consequence, addition of PEG may be cut down, or even, avoided.
