Removal of aromatic impurities from an alkene stream using an acid catalyst

A process for the preparation of a chemical composition comprising an aromatic compound α in a concentration B by weight, based on the total weight of the chemical composition, comprising:

• a. providing the following reaction components:
• i. a chemical composition comprising the following:
• a) The aromatic compound α 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, wherein the olefin is a C4-C10 olefin, and
• ii. an acidic solid;
• and
• b. reacting the components to obtain the chemical composition comprising the aromatic compound α 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;
• wherein there is a greater than 96% reduction of benzene impurities by weight in the chemical composition.
