摘要： 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.

摘要： A process for producing heavy alkyl aromatics is presented. The process utilizes low molecular weight hydrocarbons for generating larger alkyl groups. The hydrocarbons can be generated from a variety of sources including Fischer-Tropsch liquids. The process includes oligomerization of low molecular weight olefins to larger olefins. The larger olefins are passed to an alkylation reactor to alkylate aromatic compounds.
