Abstract

PURPOSE: An L-type zeolite containing Cs and at least one of Na, Li and K in specific proportions is used as a selective adsorbent, thus producing high-concentration and high-purity p-xylene from C8 aromatic hydrocarbon isomer mixtures.
CONSTITUTION: A mixture of C8 aromatic hydrocarbon isomers containing p-xylene is brought into contact with an L-type zeolite containing (a) Cs and (b) at least one selected from Na, Li and K wherein the weight ratio of a/b is 1/1W1000/1, preferably 2/1W700/1, preferably an L-type zeolite of the formula (M is metal of (a) and (b); n is the valency of M; w is 6.4±0.5; × is 0W7; Li and K is especially preferred as component b and isomers other than p-xylene is adsorbed thereon. The zeolite adsorbing isomers is removed and high-concentration and high-pyrity p-xylene remains.
