| 英文摘要 | the carbonylation of dimethyl ether to methyl acetate over h-mordenite (hmor) and pyridine-modified hmor was compared. the catalytic stability of hmor was improved significantly by pyridine pre-adsorption, and a yield of methyl acetate similar to 30% was still obtained after 48 h on stream at 473 k. in situ infrared spectroscopy and ammonia temperature-programmed desorption revealed that pyridine preferentially occupied the acidic sites in 12-membered ring pores but not the acidic sites in 8-membered ring pores. (129)xe nmr studies suggested that the channels of hmor were blocked by coke in the reaction but those in the pyridine-modified hmor were not. the acidic sites in the 12-membered ring pores were responsible for the deactivation of hmor, and the reaction can be directed to occur mainly on the acidic sties in the 8-membered ring pores by the selective adsorption of pyridine in the 12-membered ring pores. |
