Abstract

Processes for separating benzene from a stream with non-aromatics. The benzene is selectively adsorbed onto an adsorbent. The non-aromatics may be passed to a cracking section and a hot effluent from the cracking zone may be used to desorb the benzene from the adsorbent. Also hydrogen may be used to desorb the benzene. The adsorption section including the adsorbent may include two or more vessels being operated in alternating modes between adsorption and desorption.
