AGGLOMERATED ZEOLITIC ADSORBENTS, THEIR METHOD OF PREPARATION AND THEIR USES

摘要

PROBLEM TO BE SOLVED: To provide a method of recovering very pure paraxylene from an isomer mixture of an aromatic hydrocarbon having 8 carbon atoms.

SOLUTION: The method of recovering high purity of paraxylene from isomer fractions of 8C aromatic hydrocarbon in liquid phase or gas phase uses agglomerated zeolitic adsorbents which comprise zeolite X powder with an Si/Al atomic ratio being 1.15COPYRIGHT: (C)2012,JPO&INPIT
