Abstract
Aromatic by-products are sorbed from mono-olefin-containing feedstocks of olefins having from about 6 to 22 carbon atoms per molecule that contain aromatic by-products having from 7 to 22 carbon atoms per molecule. A benzene-containing regenerant displaces and desorbs the aromatic by-products from the sorbent and a regeneration effluent is provided. The regeneration effluent is treated in a regeneration effluent distillation system to provide a benzene-rich stream and an aromatic by-products-containing stream. The latter is subjected to benzene-forming conditions and recycled to the regeneration effluent distillation system where benzene is recovered.
