Removal of aromatic impurities from an alkene stream using an acid catalyst, such as a lewis acid

Abstract

A process for the preparation of a chemical composition comprising an aromatic compound a in a concentration B by weight, based on the total weight of the chemical composition, including: a. providing the following reaction components: i. a chemical composition comprising the following: a) The aromatic compound a in a concentration A by weight based on the total weight of the chemical composition, and b) An olefin in an amount of about 50 to about 99.99 wt. %, based on the total weight of the chemical composition, and ii. an acid; and b. reacting the components to obtain the chemical composition comprising the aromatic compound a in a concentration B by weight based on the total weight of the chemical composition; wherein the concentration B is less than the concentration A.
