| 英文摘要 | zeolite zsm-5, for catalyzing shape-selective disproportionation of ethylbenzene (eb) to produce para-diethylbenzene (p-deb), was modified by chemical liquid deposition of silica (sio2-cld), chemical vapor deposition of silica (sio2-cvd), loading mgo and sio2-cld and loading mgo. the results show that zsm-5 modified by sio2-cld (sio2-cld/zsm-5) has better catalytic performance than zsm-5 modified by sio2-cvd (sio2-cvd/zsm-5) due to passivation of partial acidic sites in channels of sio2-cvd/zsm-5. when sio2-cld/zsm-5 is further modified by a loading of 0.50 wt% mgo to zsm-5, it decreases both in acidic amount and in acidic strength, and its catalytic activity decreases slightly. but, the residual acidic sites on the external surface of sio2-cld/zsm-5 are well eliminated. as a result, mgo modification improves paradiethylbenzene selectivity (p-deb to deb) up to 98.6% with appreciable eb conversion of 28.1%, and it greatly reduces the side reaction of eb dealkylation. besides, zsm-5 modified by sio2-cld and mgo (sio2-cld and mgo/zsm-5) shows a good stability due to proper modification of its acidity and structure.
