摘要:
The invention relates to a method for separating meta -xylene from C8 aromatic fractions, using a zeolitic adsorbent based on sodium-exchanged or sodium-and-lithium-exchanged agglomerated crystals of zeolite Y, with a large external surface area.
摘要:
The invention relates to zeolitic absorbents based on at least one zeolite with hierarchical porosity, containing barium or barium and potassium, to the uses thereof for separating para-xylene from aromatic fractions containing 8 carbon atoms, and to the method for separating para-xylene from aromatic fractions containing 8 carbon atoms.
摘要:
The present invention relates to a zeolite absorbent comprising at least one FAU zeolite with hierarchical porosity and comprising barium or barium and potassium, and the external surface area of which is greater than 20 m 2 .g -1 , and the non-zeolite phase content being between 6% and 12% by weight with respect to the total weight of the absorbent. The present invention also relates to the use of such a zeolite absorbent as an adsorption agent, as well as the method for separation of para -xylene from aromatic isomer fractions with 8 carbon atoms.
摘要:
The invention relates to zeolitic adsorbents based on agglomerated crystals of zeolite X comprising barium, potassium and sodium. These adsorbents are applicable in the separation of fractions of aromatic C8 isomers, especially xylenes.
