A method for selectively separating benzene from gasoline boiling range streams by first fractionating the stream to produce a C.sub.6 heartcut fraction which is then passed to an adsorption zone comprised of a bed of solid adsorbent material capable of selectively removing benzene from the stream. The absorbent is regenerated with a suitable desorbent, preferably toluene.

Benzene removal from a heartcut fraction of gasoline boiling range

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.
