| Abstract: | A synthesized Y -zeolite molecular sieve was modified, and its effect on the liquid phase transalkylation reaction in the ethyl benzene preparation process with benzene and ethanol was investigated. The catalyst of high activity and good stability was prepared based on the research. The liquid phase transalky- lation reaction in the ethyl benzene production process with benzene and ethanol was studied, and the pre- ferred process conditions identified through experiments are reaction temperature： 120 to 120℃, reaction pressure： 3.0 to 3.8 MPa, mass ratio of benzene to diethylbenzene： 2.0 to 8.0, total space velocity of materials： 0.5 to3.3 h-1. |
| Keywords: | benzene ethanol ethyl benzene transalkylation molecular sieve |
