ABSTRACT:
A method for selectively separating benzene from gasoline boiling range streams by first passing the stream to an adsorption zone comprised of an adsorbent capable of selectively adsorbing benzene from the stream. A substantially benzene-free stream results and the adsorbent is regenerated by treating it with a desorbent solvent capable of desorbing benzene from the solid adsorbent.
