摘要:
The invention relates to a method for separating xylenes by means of a simulated mobile bed using an agglomerated zeolitic adsorbent solid, preferably based on faujasite zeolite with a Si/Al ratio of between 1 and 6, said solid being used in the form of particles having a diameter of between 150 μm et 500 μm.
摘要:
The invention relates to a method for the production of paraxylene from a fraction containing xylenes and ethylbenzene, said method using two simulated moving bed adsorption units and two isomerisation units.
摘要:
The invention relates to a method for the production of high-purity paraxylene from a xylene fraction, said method using a simulated moving bed separation unit and two isomerisation units, one being in the gas phase and the other in the liquid phase.
摘要:
The invention relates to a method for the production of high-purity paraxylene from a xylene fraction that can contain ethylbenzene and C9 compounds, said method using two simulated moving bed separation units operating in series and two isomerisation units.
