Direct separation of ethylbenzene from octacyclotetrahydrocarbons technology
Thread Content
What are the current techniques for separating ethylbenzene from octa-cycloalkanes?
Separation of octacyclic aromatics to isolate p-xylene and o-xylene, with ethylbenzene as a by-product； Of course, there is also the conversion of octacyclotetrahydrocarbenes into styrene ； We can discuss it together.
Xylene isomers are separated by adsorption. Since ethylbenzene has a boiling point close to that of xylene, using too many distillation trays would be necessary; therefore, ethylbenzene is usually converted – option 1 involves isomerizing ethylbenzene into xylene, while option 2 involves dealkylating ethylbenzene to produce benzene.
