ABSTRACT:
A process is disclosed for the alkylation of aromatics by charging a hydrocarbon feed containing aromatic hydrocarbons and olefinic hydrocarbons to a distillation column for separation into at least one fraction; removing an aromatics/olefin stream containing at least a portion of the aromatic hydrocarbons and at least a portion of the olefinic hydrocarbons; charging the aromatics/olefin stream to an alkylation reactor, operated at a temperature in the range of from about 80° C. to about 220° C., for alkylation of at least a portion of the aromatic hydrocarbons with the olefinic hydrocarbons; recycling at least a portion of the resulting reactor effluent to the distillation column; and removing a product stream containing alkylated aromatics from the distillation column.
