Process for co-production and separation of ethylbenzene and paraxylene |
摘要 |
Paraxylene and ethylbenzene are produced from an aromatic hydrocarbon feedstock by using adsorption zones in a simulated fluid bed. The feedstock is first passed into a first adsorption zone to produce a first paraxylene-rich fraction and a second ethylbenzene-rich fraction. The second fraction is then passed into a second adsorption zone to produce a third fraction containing essentially pure ethylbenzene and a fourth fraction containing a majority of orthoxylene and metaxylene. The fourth stream is then passed into an isomerization zone to produce an isomerate which is then recycled back to the first adsorption zone.
