Method of producing activated clay for treating aromatic hydrocarbons

Image Number 3 for United States Patent #6120595.

The present invention provides an activated clay for refining aromatic hydrocarbons such as BTX (benzene, toluene, xylene), etc., satisfying the requirements of both excellent life and excellent side-reaction-preventing property. The activated clay for treating aromatic hydrocarbons is obtained by treating dioctahedral smectite clay minerals with an acid so as to possess a BET specific surface area of not smaller than 250 m.sup.2 /g and to contain iron in an amount of not smaller than 2.5% by weight calculated as Fe.sub.2 O.sub.3.
