摘要：
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.
