| Title of Invention | METHOD OF PREPARING ALKYL AROMATIC HYDROCARBONS |
|---|---|
| Abstract | Systems and methods to produce branched alkyl aromatic hydrocarbons are described. Systems may include a hydrogenation unit, a dehydrogenation unit, an isomerization unit, an alkylation unit and a separation unit. Methods for producing branched alkyl aromatic hydrocarbons may include hydrogenation, dehydrogenation, and isomerization of olefins in a process stream. The produced olefins may be used to alkylate aromatic hydrocarbons to form branched alkyl aromatic hydrocarbons. After alkylation of the aromatic hydrocarbons, unreacted components from the alkylation process may be separated from the alkyl aromatic hydrocarbos. The unreacted components from the alkylation process may be recycled back into the main process stream or sent to other processing units. |
