英文摘要	dimethyl ether carbonylation to methyl acetate was comparatively investigated over mordenite supported copper (cu/hmor) catalysts prepared by different methods including evaporation, urea hydrolysis, incipient wetness impregnation and ion-exchange. the results showed that cu/hmor prepared via iron-exchange method exhibited the highest catalytic activity due to the synergistic effect of active-site metal and acidic molecular sieve support. conversion of 95.3% and methyl acetate selectivity of 94.9% were achieved under conditions of 210 degrees c, 1.5 mpa, and gshv of 4883 h(-1). the catalysts were characterized by nitrogen absorption, x-ray diffraction, nh3 temperature program desorption, and co temperature program desorption techniques. it was found that cu/hmor prepared by ion-exchange method possessed high surface area, moderate strong acid centers, and co adsorption centers, which improved catalytic performance for the reaction of co insertion to dimethyl ether.
