PROCESS FOR PRODUCING ALKYLBENZENES USING A CATALYST BASED ON A DEALUMINIZED Y ZEOLITE AND A CATALYST BASED ON A DEALUMINIZED MORDENITE |
摘要 |
The invention relates to a process for producing an alkylbenzene from benzene and an aliphatic mono-olefin in the presence of a catalyst based on a dealuminized Y zeolite with a molar ratio SiO2/Al2O3 ranging from 8 to 70, the product of this reaction being afterwards fractionated into a first fraction containing non converted benzene and a mono-alkylbenzene and a second fraction containing a poly-alkylbenzene, said second fraction reacting then with benzene in the presence of a catalyst based on a dealuminized mordenite with a total atomic ratio Si/Al ranging from 30 to 80. The invention especially applies to the production of ethylbenzene and cumene respectively from ethylene and propene.
