Abstract: An adsorbent for separating para-isomers from C8 or C10 aromatic hydrocarbons, specifically, a faujasite zeolite wherein about 2.5 to 25 percent, based on the total exchangeable cation sites originally present within the faujasite zeolite, is decationized and metal ions at the residual cation sites are exchanged substantially with potassium and/or barium ions. The adsorbent is used in separating the par-isomer, which is isolated by desorbing from the adsorbent.
