| 英文摘要 | hzsm-11 zeolite supported zn catalysts with different zn contents (xzn/hzsm-11a) were prepared. in the alkylation of benzene with dimethyl ether (dme) in a fixed bed reactor, the catalyst with zn content of 6 wt% (6zn/hzsm-11a) showed appropriate performance. focus was put on the comparison between 6zn/hzsm-5 and 6zn/hzsm-11 with the same crystal size of 600-800 nm, and also with the similar bet surface area, micropore volume, si/al2 molar ratio, and acidity. in the alkylation of benzene with dme, the 6zn/hzsm-11 showed better activity and stability, and especially enhanced the conversion of benzene and selectivities to xylene and trimethylbenzene, compared with the 6zn/hzsm-5. this was mainly related to the higher adsorption capacity and adsorption-desorption rates to the three adsorbates (benzene, m-xylene and 1,3,5-trimethylbenzene) over the 6zn/hzsm-11 in comparison with the 6zn/hzsm-5. |
