摘要:
Metaxylene is recovered from a mixture of C.sub.8 aromatic hydrocarbons including other xylenes by liquid phase adsorptive separation using a sodium or sodium and lithium exchanged Y zeolite as the adsorbent. Performance is improved by maintaining the adsorbent in a narrow range of temperature and hydration. Toluene is the preferred desorbent.
