Claim:
1. A process for producing alkylaromatic compounds comprising: contacting an aromatic compound and an olefin in an alkylation reaction zone under alkylation conditions in the presence of an alkylation catalyst to produce an alkylation product containing monoalkylaromatic compounds, dialkylaromatic compounds, and unreacted aromatic compound; separating the alkylation product in a separation zone into an unreacted aromatic fraction and a fraction containing the monoalkylaromatic compounds and the dialkylaromatic compounds; regenerating a spent alkylation reaction zone by passing an aromatic compound stream through the spent alkylation zone at a regeneration temperature above an alkylation temperature to provide a regeneration aromatic compound stream; and introducing at least about 80 wt % of the regeneration aromatic compound stream directly into the alkylation zone, the regeneration aromatic compound stream being at the alkylation temperature.
