ABSTRACT:
Selective adsorption of one cyclic compound from a fluid mixture with a structurally similar cyclic compound can be obtained with molecular sieves (crystalline aluminosilicate zeolites) which have been partially dehydrated at a temperature in the range of 80.degree.-300.degree.C. Preferably the Al/Si ratio in the zeolite framework is in the range of 0.2-0.65. For example, m-xylene can be separated from p-xylene by selective adsorption of the m-xylene on NaY zeolite which was partially dehydrated at 125.degree. C. and contains about 12 wt % water by ignition analysis.
