ALKYLATION OF BENZENE UTILIZING FISCHER-TROPSCH OLEFIN-PARAFFIN MIXTURES

摘要

Paraffin-olefin mixtures synthesized by the Fischer-Tropsch process are used to alkylate benzene at high temperatures in the presence of an aluminum chloride catalyst at low catalyst volume to feed volume ratios. The paraffins are separated from the alkylation effluent and are recycled to a chlorination step from which the paraffin-chloroparaffin effluent mixture is combined with the fresh feed Fischer-Tropsch olefin-paraffin mixture and the combined feeds are used to alkylate the benzene.
